The Future Of Human Evolution Essay -- essays research papers

The Future of Human EvolutionEvolution, the science of how worlds of living organisms wobble overtime in response to their environment, is the central unifying theme in biologytoday. Evolution was first explored in its semi-modern form in Charles Darwin s1859 book, fount of Species by means of inherent Selection. In this book, Darwinlaid out a strong argument for evolution. He postulated that all species have acommon base from which they are descended. As populations of species movedinto new habitats and new parts of the world, they faced different environmentalconditions. Over time, these populations accumulated modifications, oradaptations, that allowed them and their offspring to survive wear in theirnew environments. These modifications were the key to the evolution of newspecies, and Darwin proposed natural selection or "survival of the fittest" asthe vehicle by which that transmit occurs. Under Natural Selection, someindividuals in a population have adaptations that allow them to survive andreproducemore than other individuals. These adaptations become more common in thepopulation because of this higher reproductive success. Over time, thecharacteristics of the population as a whole can change, sometimes evenresulting in the formation of a new species. human race have survived for thousandsof age and will most like survive thousands of more. Throughout the historyof the Huminoid species man has evolved from Homo Erectus to what we today callHomo Sapiens, or what we get laid today as modern man.. The topic of this paper iswhat does the future have in store for the evolution of Homo Sapiens. Of course,human beings will cut through to change culturally therefore cultural evolutionwill always continue solely what of physiological evolution? The culturalevolution of man will continue as long as man can think after all its theideas we think up that makes up our cultures. In a thousand years man mightcomplete a 180 degree turn culturally (not to mention physiologically) and asseen by our fellow inhabitants of earth we would in center be different beings.One can say that this new culture has chosen its ideas based on NaturalSelection. One can see this in the spread of ideas in the past history of homosapiens, the ideas which cause man to succeed are chosen such as science anddemo... ... haphazard genetic drift,but it may become homozygous for allele "A", whereas the first population hasbecome homozygous for allele "a". As time goes on, isolated populations stragglefrom each other, each losing heterozygosity. The variation originally presentwithin populations now appears as variation between populations (Suzuki 704).The evolution of man can be broken in up into three basic stages. The first,lasting millions of years, slowly shaped human temperament from Homo erectus to Homesapiens. Natural selection provided the means for countless random mutationsresulting in the appearance of such human characterist ics as hands and feet.The second stage, after the full development of the human body and mind, sawhumans go from wild foragers to an agriculture based society. Naturalselection received a helping hand as man took advantage of random mutations innature and bred more productive species of plants and animals. The mostbountiful wheats were collected and re-planted, and the fastest horses were bredwith equally faster horses. Even in our recent history the strongest black maleslaves were copulate with the hardest working female slaves.
