The Future Of Human Evolution Essay -- essays research papers

The Future of Hu art object EvolutionEvolution, the experience of how communitys of living organisms change over measure in response to their environment, is the fundamental unifying theme in biologytoday. Evolution was first gear explored in its semi-modern form in Charles Darwin s1859 book, Origin of Species by means of innate Selection. In this book, Darwinlaid out a strong argument for ontogenesis. He postulated that all(a) species have acommon ancestor from which they are descended. As populations of species travelinto refreshed habitats and immature parts of the world, they faced different environmentalconditions. oer time, these populations accumulated modifications, oradaptations, that allowed them and their offspring to die better in theirnew environments. These modifications were the key to the evolution of newspecies, and Darwin proposed natural selection or " natural selection of the fittest" asthe vehicle by which that change occurs. Under Natural Selec tion, nearlyindividuals in a population have adaptations that allow them to survive andprocreate more than 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. Hu musical compositions have survived for thousandsof years and will most like survive thousands of more. Throughout the historyof the Huminoid species man has evolved from kind beings Erectus to what we today callHomo Sapiens, or what we know today as modern man.. The topic of this piece iswhat does the future have in store for the evolution of Homo Sapiens. Of course,human beings will continue to change culturally therefore cultural evolutionwill always continue but 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 cult ures. In a thousand years man talentcomplete a 180 degree turn culturally (not to take down physiologically) and asseen by our fellow inhabitants of earth we would in essence be different beings.One can say that this new culture has elect 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(prenominal) as science anddemo... ...random inheritable drift,but it may become homozygous for allele "A", whereas the first population hasbecome homozygous for allele "a". As time goes on, isolated populations divergefrom each other, each losing heterozygosity. The variation originally exemplifywithin populations now appears as variation between populations (Suzuki 704).The evolution of man can be broken up into three basic stages. The first, durable millions of years, slowly shaped human nature from Homo erectus to Homesapiens. Natural selection provided the mean s for countless random mutationsresulting in the appearance of such human characteristics as collapses and feet.The second stage, after the full ripening of the human body and mind, sawhumans moving from wild foragers to an culture 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 red-hot horses. Even in our recent history the strongest black maleslaves were pair with the hardest working female slaves.
