The Future Of Human Evolution Essay -- essays research papers

The Future of Hu world EvolutionEvolution, the science of how cosmoss of sustentation organisms change overtime in response to their environment, is the central integrate theme in biologytoday. Evolution was first explored in its semi-modern spurt in Charles Darwin s1859 book, Origin of Species by means of Natural Selection. In this book, Darwin primed(p) out a strong argument for organic evolution. He postulated that all species piddle acommon ancestor from which they are descended. As populations of species movedinto brisk habitats and new parts of the world, they faced disparate environmentalconditions. Over time, these populations compile modifications, oradaptations, that allowed them and their offspring to survive better in theirnew environments. These modifications were the samara to the evolution of newspecies, and Darwin proposed natural woof or "survival of the fittest" asthe vehicle by which that change occurs. Under Natural Selection, someindividuals in a population have adaptations that allow them to survive andreproduce more(prenominal) than other individuals. These adaptations become more common in thepopulation because of this high re robust success. Over time, thecharacteristics of the population as a whole back tooth change, sometimes evenresulting in the formation of a new species. worldly concern have survived for thousandsof years and result most like survive thousands of more. end-to-end the historyof the Huminoid species man has evolved from Homo Erectus to what we today callHomo Sapiens, or what we know today as modern man.. The topic of this paper iswhat does the time to come have in store for the evolution of Homo Sapiens. Of course, tender-hearted beings leave behind continue to change culturally therefore cultural evolutionwill always continue exactly what of physiological evolution? The culturalevolution of man will continue as long as man fecal matter think after all its theideas we think up that makes up our cultures. In a thousand years man might effected a 180 degree turn culturally (not to mention physiologically) and asseen by our fellow inhabitants of earth we would in essence be different beings.One can say that this new culture has chosen its ideas establish on NaturalSelection. One can see this in the mete out of ideas in the past history of homosapiens, the ideas which cause man to stick with are chosen such as science anddemo... ...random genetic drift,but it may become homozygous for allele "A", whereas the first population hasbecome homozygous for allele "a". As time goes on, obscure populations divergefrom each other, each losing heterozygosity. The variation originally present at heart populations now appears as variation between populations (Suzuki 704).The evolution of man can be broken up into three basic stages. The first,lasting millions of years, easy shaped tender nature from Homo erectus to Homesapiens. Natural selection provided the mean s for countless random mutationsresulting in the appearance of such human characteristics as hands and feet.The second stage, after the full development of the human body and mind, sawhumans moving from wild foragers to an agriculture establish 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. level in our recent history the strongest black maleslaves were mated with the hardest working(a) female slaves.
