My Fathers Prostitute By Steven Whitacre - 1871 Words

Steven Whitacre experienced a very traumatic childhood of abuse from his father which led to a very difficult adulthood. In his book â€Å"My Fathers Prostitute†, he talks about his life, starting out when his father first abused him to more recent times in adulthood to where he finally sought help and started to move on in his life started to live the life he should and deserves. This book really opened my eyes on what all goes on in this world that I would have never guessed. â€Å"Every eight minutes, a child is sexually assaulted in the U.S., and 93% know the perpetrator† (â€Å"Adult Survivors of Childhood†). To me this statistic seems insane and I cannot ever imagine being sexually assaulted by anyone let alone one of my parents that I am supposed to trust and love. When you really think about it, that how every eight minutes a child is getting sexually assaulted it is astonishing. It makes me wonder how many people I know that I have been sexually assaulte d but don’t tell anyone. I assume there are many different cases of sexual assault and how there are different levels of how traumatic they are to the individual someone came upon. With some people, the sexual assault only happened once, and with others like the author of My Fathers Prostitute it happens during their entire childhood to impact the individual even more. I am not saying that the individuals who have only been sexually assaulted once came out un hurt or traumatized, but I would just imagine that it would not leaveShow MoreRelatedSummary Of My Father s Prostitute By Steven Whitacre2060 Words   |  9 Pages11/6/17 Book Analysis: My Father’s prostitute â€Å"My Father’s Prostitute† by Steven Whitacre, is an honest and chilling book about an innocent boy’s struggle from child to adulthood.

Impressionism and Post Impressionism Essay - 2229 Words

Expressive Essay In this essay, I will contrast and compare the two art movements, Impressionism, and Post-Impressionism. I will be concentrating on the works of the two leading artists of these styles Claude Monet and Vincent van Gogh. The impressionist movement is often considered to mark the beginning of the modern period of art. It was developed in France during the late 19th century. The impressionist movement arose out of dissatisfaction with the classical, dull subjects and clean cut precise techniques of painting. They preferred to paint outdoors concentrating more on landscapes and street scenes, and began to paint ordinary everyday people and liked to show the effects in natural light. Claude Monet is often†¦show more content†¦Aside from the dark shadows the painting is done in light, bright colours and once again Monet shows his skill in portraying a nice sunny day by the riverside. He has managed to give the impression of calm rippling water by using rough brushstrokes. He uses a mix of light and darker colours to show the sun glistening across the water. The painting creates a rel axing and the light colours, calm water and slow moving boats create pleasant mood, which I think. I like this painting and I especially like the way in which Monet has created many different areas that show a range of colours, techniques and all add something different to the painting. This variety draws you in and shows a real commitment and dedication to detail. These two paintings have many similarities, however they both show different sides to Monets style of painting. Le Grenouillere has much thicker brushstrokes and concentrates on darker colours such as greens and browns. In the Road- Bridge he tends to use much lighter yellows and blues and his brushstrokes are much shorter and rougher. This creates quite different moods and the second painting has a much sunnier and happier mood. The paintings are very similar in that the effects of the sun bouncing across the water plays a key part in both paintings.

OCD free essay sample

â€Å"When I read, I’m taken away,† my eight-year-old hand scripted in an early attempt at poetry. It is true that, as with Sara Crewe, The Little Princess with a big imagination, most of my seventeen years have been spent somewhere other than the world inhabited by my contemporaries. However, far from living another’s story, I have lived a life that is wonderfully and uniquely my own, one that has been immeasurably enriched by the parallel literary worlds in which I have dwelt. Early on, my love of books helped me stand up to a well-meaning but exacting teacher who solemnly insisted that the words â€Å"and† and â€Å"because† must never start a sentence. Defiantly, I called on my good friend Pippi Longstocking, pointing out a complete and published sentence by a celebrated author: â€Å"And Pippi jumped into the lake.† I was no troublemaker, but I nonetheless insisted that if Pippi was wrong, I had no desire to be right. We will write a custom essay sample on OCD or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The teacher’s response? â€Å"You’re not Pippi.† I vowed that day to be more like Miss Longstocking—not to mention her creator, Astrid Lindgren—daring enough not only to jump into a lake fully clothed, but to begin my sentences with a bold conjunction. And, I am proud to report, since then I have successfully attempted both feats. In middle school, the same spell that forced me to obey obsessive compulsions, I discovered, held poor Ella Enchanted. The doctor’s diagnosis of Obsessive Compulsive Disorder marked the beginning of a scary and frustrating journey where I felt as if I had lost control of everything in my life, including my own actions. Throughout those difficult years, by holding the figurative hand of my magical counterpart, I was able to confront my inner demons (which were slightly different in form, and yet no less formidable, than the giant trolls which held Ella captive) and emerge a stronger person. Despite my newfound strength, I was blindsided by the fallout following an extremely opinionated opinion piece I wrote for my school newspaper. I learned the disastrous effects a few well-chosen words could have on a girl who was, quite frankly, never very popular to begin with when my condemnation of the school’s policy of selling junky snacks actually helped lead to the removal of said snacks. My mighty pen had spoken, and a sympathetic friend became as hard to find as a bag of Doritos under the new regime. Blameless (or so I insisted), and yet condemned like Stanley Yelnats (who, you may recall, was forced to dig Holes), I stood proudly next to Howard Roark, The Fountainhead of inner strength, and both ignored the taunts of society and continued to pursue my passion for journalism. Although some still doubt me, I, like the eccentric Willy Wonka, moved on and created my own high school legacy; minus the chocolate, of course. Following in my size-seven footsteps, nine years behind and yet, in many ways, light years ahead, is my brother Zack. Years of sharing literature have caused our bond to grow closer and infinitely more positive than that joining The Boy Who Lived and the Dark Lord. As Voldemort’s fruitless attempts to defeat Harry Potter are recounted by my expressive and animated reading voice, there is indeed something magical about the variety of characters that come to life before us each night. Sharing my life with the countless two-dimensional friends I have made throughout the years has shaped me into the person who now stands before you. Recognizing myself in the fervent glow of my brother’s eyes as I share these companions with him allows me to stare unflinchingly ahead, with full confidence in who I am and who I hope to become.

Untitled Essay, Research Paper BODYINTRODUCTION TO EVOLUTION What is Evolution? Development is the procedure by which all life thingshave developed from crude beings through alterations happening overbillions of old ages, a procedure that includes all animate beings and workss. Precisely howevolution occurs is still a affair of argument, but there are many differenttheories and that it occurs is a scientific fact. Biologists agree that all livingthings come through a long history of alterations shaped by physical andchemical procedures that are still taking topographic point. It is possible that all organismscan be traced back to the beginning of Life from one celled organims.The most direct cogent evidence of development is the scientific discipline of Paleontology, orthe survey of life in the yesteryear through dodo remains or feelings, normally inrock. Changes occur in life beings that serve to increase theiradaptability, for endurance and reproduction, in altering environments.Evolution seemingly has no constitutional way intent. We will write a custom essay sample on Untitled Essay Research Paper BODYINTRODUCTION TO EVOLUTION or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page A given sort oforganism may germinate merely when it occurs in a assortment of signifiers differing inhereditary traits, that are passed from parent to offspring. By opportunity, somevarieties prove to be badly adapted to their current environment and thusdisappear, whereas others prove to be adaptative, and their Numberss increase.The riddance of the unfit, or the endurance of the fittest, is known asNatural Selection because it is nature that discards or favours aarticular being. Evolution takes topographic point merely when natural choice operates on apopulation of beings incorporating diverse inheritable signifiers. History Pierre Louis Moreau de Maupertuis ( 1698-1759 ) was the first topropose a general theory of development. He said that familial stuff, dwelling of atoms, was transmitted from parents to offspring. His opinionof the portion played by natural choice had small influence on other naturalists. Until the mid-19th century, naturalists believed that each species wascreated individually, either through a supreme being or through spontaneousgeneration the construct that organisms arose to the full developed from dirt or H2O. Thework of the Swedish naturalist Carolus Linnaeus in progressing the sorting ofbiological beings focused attending on the close similarity between certainspecies. Guess began as to the being of a kind of blood relationshipbetween these species. These inquiries coupled with the emerging scientific disciplines ofgeology and palaeontology gave rise to hypotheses that the life-forms of the dayevolved from earlier signifiers through a procedure of alteration. Highly of import wasthe realisation that different beds of stone represented different clip periods andthat each bed had a typical set of dodos of life-forms that had lived in the yesteryear. Lamarckism Jean Baptiste Lamarck was one of several theoreticians who proposed anevolutionary theory based on the usage and neglect of variety meats. Lamarck stated thatan single acquires traits during its life-time and that such traits are in some wayput into the familial stuff and passed to the following coevals. Thiswas an effort to explicate how a species could alter bit by bit over time.According to Lamarck, camelopard, for illustration, have long cervixs because for manygenerations single giraffes stretched to make the uppermost foliages of trees, ineach coevals the camelopard added some length to their cervixs, and they passed thison to their progeny. New variety meats arise from new demands and develop inthe extent that they are used, neglect of variety meats leads totheir disappearing. Subsequently, the scientific discipline of Genetics disproved Lamarck # 8217 ; s theory, itwas found that acquired traits can non be inherited. Malthus Thomas Robert Malthus, an English reverend, through his work An Essayon the Principle of Population, had a great influence in directing naturalists towarda theory of natural choice. Malthus proposed that environmental factors such asfamine and disease limited population growing. Darwin After more than 20 old ages of observation and experiment, Charles Darwinproposed his theory of development through natural choice to the Linnean Societyof London in 1858. He presented his find along with another Englishnaturalist, Alfred Russel Wallace, who independently discovered natural choice atabout the same clip. The undermentioned twelvemonth Darwin published his full theory, supported with tremendous grounds, in On the Origin of Species. Geneticss The part of genetic sciences to the apprehension of development hasbeen the account of the heritage in persons of the same species. GregorMendel discovered the basic rules of heritage in 1865, but his work wasunknown to Darwin. Mendel # 8217 ; s work was rediscovered by other scientists around1900. From that clip to 1925 the scientific discipline of genetic sciences developed quickly, and manyof Darwin # 8217 ; s thoughts about the heritage of fluctuations were found to be incorrect.Only since 1925 has natural choice once more been recognized as essentialin development. The modern theory of development combines the findings of moderngenetics with the basic model supplied by Darwin and Wallace, making thebasic rule of Population Genetics. Modern population genetic sciences was developedlargely during the 1930s and # 8217 ; 40s by the mathematicians J. B. S. Haldane and R. A.Fisher and by the life scientists Theodosius Dobzhansky, Julian Huxley, Ernst Mayr, George Gaylord SIMPSON, Sewall Wright, Berhard Rensch, and G. LedyardStebbins. Harmonizing to the theory, variableness among persons in a population ofsexually reproducing beings is produced by mutant and geneticrecombination. The resulting familial variableness is capable to natural choice in theenvironment. Population GENETICS The word population is used in a particular sense to depict development. Thestudy of individual persons provides few hints as to the possible results ofevolution because individual persons can non germinate in their life-time. An individualrepresents a shop of cistrons that participates in development merely when those cistrons arepassed on to farther coevalss, or populations. The cistron is the basic unit in thecell for conveying familial features to offspring. Persons are unitsupon which natural choice operates, but the tendency of development can be tracedthrough clip merely for groups of crossbreeding persons, populations can beanalyzed statistically and their development predicted in footings of norm Numberss. The Hardy-Weinberg jurisprudence, which was discovered independently in 1908 bya British mathematician, Godfrey H. Hardy, and a German doctor, WilhelmWeinberg, provides a criterion for quantitatively mensurating the extent ofevolutionary alteration in a population. The jurisprudence states that the cistron frequences, orratios of different cistrons in a population, will stay changeless unless they arechanged by outside forces, such as selective reproduction and mutant. Thisdiscovery reestablished natural choice as an evolutionary force. Comparing theactual cistron frequences observed in a population with the frequences predicted, bythe Hardy-Weinberg jurisprudence gives a numerical step of how far the populationdeviates from a nonevolving province called the Hardy-Weinberg equilibrium. Given alarge, indiscriminately engendering population, the Hardy-Weinberg equilibrium will holdtrue, because it depends on the Torahs of chance. Changes are produced in thegene pool through mutants, cistron flow, familial impetus, and natural choice. Mutant A mutant is an inheritable alteration in the character of a cistron. Mutationsmost frequently occur spontaneously, but they may be induced by some externalstimulus, such as irradiation or certain chemicals. The rate of mutant in worlds isextremely low ; however, the figure of cistrons in every sex cell, is so big thatthe chance is high for at least one cistron to transport a mutant. Gene Flow New cistrons can be introduced into a population through new breedingorganisms or gametes from another population, as in works pollen. Gene flow canwork against the procedures of natural choice. Familial Drift A alteration in the cistron pool due to opportunity is called familial impetus. Thefrequency of loss is greater the smaller the population. Therefore, in little populationsthere is a inclination for less fluctuation because couples are more similar genetically. Natural Choice Over a period of clip natural choice will ensue in alterations in thefrequency of allelomorphs in the cistron pool, or greater divergence from the nonevolvingstate, represented by the Hardy-Weinberg equilibrium. New SPECIES New species may germinate either by the alteration of one species to another orby the splitting of one species into two or more new species. Splitting, thepredominant manner of species formation, consequences from the geographical isolation ofpopulations of species. Isolated populations undergo different mutants, andselection force per unit areas and may germinate along different lines. If the isolation is sufficientto prevent crossbreeding with other populations, these differences may becomeextensive plenty to set up a new species. The evolutionary alterations broughtabout by isolation include differences in the generative systems of the group.When a individual group of organisms diversifies over clip into several subgroups byexpanding into the available niches of a new environment, it is said to undergoAdaptive Radiation. Darwin # 8217 ; s Finches, in the Galapagos Islands, West of Ecuador, illustrateadaptive radiation. They were likely the first land birds to make the islands, and, in the absence of competition, they occupied several ecological home grounds anddiverged along several different lines. Such forms of divergency are reflected inthe life scientists # 8217 ; strategy of categorization of beings, which groups together animalsthat have common features. An adaptative radiation followed the foremost conquestof land by craniates. Natural choice can besides take populations of different species populating insimilar environments or holding similar ways of life to germinate similar characteristics.This is called convergent development and reflects the similar selective force per unit area ofsimilar environments. Examples of convergent development are the oculus in cephalodmollusks, such as the octopus, and in craniates ; wings in insects, nonextant flyingreptiles, birds, and chiropterans ; and the flipperlike extremities of the sea polo-neck ( reptilian ) , penguin ( bird ) , and seahorse ( mammal ) . MOLECULAR EVOLUTION An spring of new grounds back uping development has come in the 20thcentury from molecular biological science, an unknown field in Darwin # 8217 ; s twenty-four hours. Thefundamental dogma of molecular biological science is that cistrons are coded sequences of theDNA molecule in the chromosome and that a cistron codifications for a precise sequence ofamino acids in a protein. Mutants alter DNA chemically, taking to modified ornew proteins. Over evolutionary clip, proteins have had histories that are astraceable as those of large-scale constructions such as castanetss and dentitions. The farther inthe yesteryear that some hereditary stock diverged into contemporary species, the moreevident are the alterations in the amino-acid sequences of the proteins of thecontemporary species. PLANT EVOLUTION Biologists believe that workss arose from the multicellular green algae ( phylum Chlorophyta ) that invaded the land about 1.2 billion old ages ago. Evidence isbased on modern green algae holding in common with modern workss the samephotosynthetic pigments, cell walls of cellulose, and multicell signifiers holding a lifecycle characterized by Alternation Of Generations. Photosynthesis about certainlydeveloped foremost in bacterium. The green algae may hold been preadapted to land. The two major groups of workss are the nonvascular plants and the vascular plants ; the two groups most likely diverged from one common group of workss. Thebryophytes, which lack complex carry oning systems, are little and are found inmoist countries. The vascular plant s are workss with efficient carry oning systems ; theydominate the landscape today. The seed is the major development in vascular plants, and it is most of import for endurance on land. Fossil grounds indicates that land workss foremost appeared during the SilurianPeriod of the Paleozoic Era ( 425-400 million old ages ago ) and diversified in theDevonian Period. Near the terminal of the Carboniferous Period, fernlike workss hadseedlike constructions. At the stopping point of the Permian Period, when the land became drierand colder, seed workss gained an evolutionary advantage and became the dominantplants. Plant foliages have a broad scope of forms and sizes, and some fluctuations ofleaves are versions to the environment ; for illustration, little, leathery foliages foundon workss in dry climes are able to conserve H2O and gaining control less visible radiation. Besides, early flowering plants adapted to seasonal H2O deficits by dropping their leavesduring periods of drouth. Evidence FOR Development The Fossil Record has of import penetrations into the history of life. The orderof dodos, get downing at the underside and lifting upward in graded stone, corresponds totheir age, from oldest to youngest. Deep Welsh stones, up to 570 million old ages old, contain the remains ofvarious marine invertebrate animate beings, sponges, Portuguese man-of-war, worms, shellfish, starfish, and crustaceans. These invertebrates were already so good developed that they musthave become differentiated during the long period predating the Welsh. Somefossil-bearing stones lying good below the oldest Welsh strata contain imprints ofjellyfish, paths of worms, and hints of soft corals and other animate beings of uncertainnature. Paleozoic Waterss were dominated by arthropods called trilobites and largescorpionlike signifiers called eurypterids. Common in all Paleozoic periods ( 570-230million old ages ago ) were the nautiloid, which are related to the modern nautilus, andthe lamp shells, or brachiopods. The uneven graptolites, colonial animate beings whosecarbonaceous remains resemble pencil Markss, attained the extremum of theirdevelopment in the Ordovician Period ( 500-430 million old ages ago ) and thenabruptly declined. In the mid-1980s research workers found fossil carnal tunnels inrocks of the Ordovician Period ; these hint dodos indicate that terrestrialecosystems may hold evolved sooner than was one time thought. Many of the Paleozoic Marine invertebrate groups either became nonextant ordeclined aggressively in Numberss before the Mesozoic Era ( 230-65 million old ages ago ) .During the Mesozoic, shelled ammonites flourished in the seas, and insects andreptiles were the prevailing land animate beings. At the stopping point of the Mesozoic the once-successful Marine ammonites perished and the reptilian dynasty collapsed, givingway to birds and mammals. Insects have continued to boom and hold differentiatedinto a astonishing figure of species. During the class of development works and animate being groups have interacted toone another # 8217 ; s advantage. For illustration, as blossoming workss have become lessdependent on air current for pollenation, a great assortment of insects have emerged asspecialists in transporting pollen. The colourss and aromas of flowers hold evolvedas versions to pull insects. Birds, which feed on seeds, fruits, and buds, haveevolved quickly in confidant association with the blossoming workss. The emergence ofherbivorous mammals has coincided with the widespread distribution of grasses, and the herbivorous mammals in bend have contributed to the development ofcarnivorous mammals. Fish and Amphibians During the Devonian Period ( 390-340 million old ages ago ) the huge land areasof the Earth were mostly populated by carnal life, salvage for rare animals likescorpions and millepedes. The seas, nevertheless, were crowded with a assortment ofinvertebrate animate beings. The fresh and salt Waterss besides contained cartilaginous andbony Fish. From one of the many groups of fish inhabiting pools and swampsemerged the first land craniates, get downing the craniates on their conquering of allavailable tellurian home grounds. Among the legion Devonian aquatic signifiers were the Crossopterygii, lobe-finned fish that possessed the ability to quaff air when they rose to the surface.These ancient air- external respiration fish represent the stock from which the foremost landvertebrates, the amphibious vehicles, were derived. Scientists continue to speculate aboutwhat led to venture onto land. The lobefins that migrated onto land wereonly crudely adapted for tellurian being, but because they did non encountercompetitors, they survived. Lobe-finned fish did, nevertheless, possess certain features that servedthem good in their new environment, including crude lungs and internal anterior nariss, both of which are indispensable for take a breathing out of the water.Such features, called preadaptations, did non develop because the others werepreparing to migrate to the land ; they were already present by accident and becameselected traits merely when they imparted an advantage to the fish on land. The early land-dwelling amphibious vehicles were thin-bodied with fishlike dress suits, butthey had limbs capable of motive power on land. These limbs likely developedfrom the sidelong fives, which contained heavy lobes that in bend contained bonyelements. The antediluvian amphibians neer became wholly adapted for being onland, nevertheless. They spent much of their lives in the H2O, and their moderndescendants, the salamanders, newts, toads, and toads # 8211 ; still must return to H2O todeposit their eggs. The riddance of a water-dwelling phase, which was achievedby the reptilians, represented a major evolutionary progress. The Reptilian Age Possibly the most of import factor lending to the going of reptilesfrom the amphibious vehicles was the development of a shell- covered egg that could be laidon land. This development enabled the reptilians to distribute throughout the Earth # 8217 ; slandmasses in one of the most dramatic adaptative radiations in biological history. Like the eggs of birds, which developed subsequently, reptilian eggs contain acomplex series of membranes that protect and nourish the embryo and aid itbreathe. The infinite between the embryo and the amniotic sac is filled with an amnioticfluid that resembles seawater ; a similar fluid is found in the foetuss of mammals, including worlds. This fact has been interpreted as an indicant that life originatedin the sea and that the balance of salts in assorted organic structure fluids did non alteration verymuch in development. The membranes found in the human embryo are essentiallysimilar to those in reptilian and bird eggs. The human yolk pouch remains little andfunctionless, and the exhibits have no development in the human embryo.Nevertheless, the presence of a yolk pouch and allantois in the human embryo is oneof the strongest pieces of grounds documenting the evolutionary relationshipsamong the widely differing sorts of craniates. This suggests that mammals, including worlds, are descended from animate beings that reproduced by agencies ofexternally laid eggs that were rich in yolk. The reptilians, and in peculiar the dinosaurs, were the dominant landanimals of the Earth for good over 100 million old ages. The Mesozoic Era, duringwhich the reptilians thrived, is frequently referred to as the Age of Reptiles. In footings of evolutionary success, the larger the animate being, the greater thelikelihood that the animate being will keep a changeless Body Temperature independentof the environmental temperature. Birds and mammals, for illustration, bring forth andcontrol their ain organic structure heat through internal metabolic activities ( a province known asendothermy, or warm-bloodedness ) , whereas today # 8217 ; s reptilians are thermally unstable ( inhuman ) , modulating their organic structure temperatures by behavioural activities ( thephenomenon of ectothermy ) . Most scientists regard dinosaurs as lumbering, oversized, inhuman lizards, instead than big, lively, animate beings with fast metabolicrates ; some life scientists, nevertheless # 8211 ; notably Robert T. Bakker of The Johns HopkinsUniversity # 8211 ; assert that a immense dinosaur could non perchance have warmed up everymorning on a cheery stone and must hold relied on internal heat production. The reptilian dynasty collapsed before the stopping point of the Mesozoic Era.Relatively few of the Mesozoic reptilians have survived to modern times ; thoseremaining include the Crocodile, Lizard, serpent, and polo-neck. The cause of the declineand decease of the big array of reptilians is unknown, but their disappearing isusually attributed to some extremist alteration in environmental conditions. Like the elephantine reptilians, most line of descents of beings have finally becomeextinct, although some have non changed appreciably in 1000000s of old ages. Theopossum, for illustration, has survived about unchanged since the late CretaceousPeriod ( more than 65 million old ages ago ) , and the Horseshoe Crab, Limulus, is notvery different from fossils 500 million old ages old. We have no account for theunexpected stableness of such beings ; possibly they have achieved an almostperfect accommodation to a unchanging environment. Such stable signifiers, nevertheless, arenot at all dominant in the universe today. The human species, one of the dominantmodern life signifiers, has evolved quickly in a really short clip. The Rise of Mammals The diminution of the reptilians provided evolutionary chances for birds andmammals. Small and invisible during the Mesozoic Era, mammals rose tounquestionable laterality during the Cenozoic Era ( get downing 65 million yearsago ) . The mammals diversified into Marine signifiers, such as the giant, mahimahi, seal, and seahorse ; fossorial ( adapted to delving ) signifiers populating underground, such asthe mole ; winging and gliding animate beings, such as the chiropteran and winging squirrel ; andcursorial animate beings ( adapted for running ) , such as the Equus caballus. These variousmammalian groups are good adapted to their different manners of life, particularly bytheir extremities, which developed from common ascendants to go specializedfor swimming, flight, and motion on land. Although there is small superficial resemblance among the arm of a individual, the fin of a giant, and the wing of a chiropteran, a closer comparing of their skeletalelements shows that, bone for bone, they are structurally similar. Biologists regardsuch structural similarities, or homologies, as grounds of evolutionary relationships.The homologous limb castanetss of all four-legged craniates, for illustration, areassumed to be derived from the limb castanetss of a common ascendant. Biologists arecareful to separate such homologous characteristics from what they call analogousfeatures, which perform similar maps but are structurally different. Forexample, the wing of a bird and the wing of a butterfly are correspondent ; both areused for flight, but they are wholly different structurally. Analogous constructions donot indicate evolutionary relationships. Closely related dodos preserved in uninterrupted sequences of stone stratahave allowed evolutionists to follow in item the development of many species as it hasoccurred over several million old ages. The lineage of the Equus caballus can be tracedthrough 1000s of dodo remains to a little terrier-sized animate being with four toes onthe front pess and three toes on the hind pess. This ascendant lived in the EoceneEpoch, approximately 54 million old ages ago. From dodos in the higher beds of stratifiedrock, the Equus caballus is found to hold bit by bit acquired its modern signifier by eventuallyevolving to a one-toed Equus caballus about like modern Equus caballuss and eventually to the modernhorse, which dates back about 1 million old ages. Decision TO EVOLUTION Although we are non wholly certain that development is how we got the manner weare now, it is a strong belief among many people today, and scientist are findingmore and more grounds to endorse up the evolutionary theory.

One of the exhibits from San Francisco academy of science museum that Essay

One of the exhibits from San Francisco academy of science museum that relates to physical anthropology - Essay Example nt life forms is to gain a detailed understanding regarding the evolution of modern species of animals, including human beings, which posit a relation to physical anthropology. Additionally, the paper attempts to highlight the behavioral patterns of these life forms. Through these exhibits, it is possible to piece together evidence of man and the life he lived in the ancient times. Such evidence makes it possible to estimate the exact period in which the said hominid lived, the habits and lifestyle he was accustomed to, as well as other dynamics he faced. Through the study of Selam, it is possible to prove numerous facts concerning the existence of early man. The Academy has the remains of an ancient child by the name Selam. These remains belong to a three-year-old child of the Australopithecus afarensis species. The fossils of Selam were discovered in Dikika in Ethiopia, four kilometers from where Lucy was found. ‘Lucy’ is believed by many archeologists to be the mother of Selam.The vestigial remains found consists of an entire torso, plus the arms and legs. Further indications suggest that the remains of Selam were buried after an event of great significance such as a flood. At the time of her death, Selam already possessed visible characteristics of her species, and these were already distinctively noticeable. The postcranial skeleton of Selam brings about many questions as to how she was able to cope with the landscape that she was in. However, research suggests that she was a creature who walked on two legs. Many researchers question how she was able to walk bipedally because its upper body contained many primitive traits. The lower body, however, shows visible adaptations that proved capability to walk. Selam had legs that were built for walking and fingers that were built for climbing. Many features on the body of this species suggest that she was also an arboreal creature (Price, 2012). Further analysis of Selam suggests that she possesses shoulder
