Human Evolution :: The Future of Human Evolution

For centuries, man has been curious nigh his origins and the origins of the life surrounding him. Countless explanations have been formulated using cause that proves the story to be true. However, in 1859, Charles Darwin published a monumental guess in his book c eached The Origin of Species. In his book, Darwin outlined his theory of phylogenesis by natural selection (Darwin, 1859). Although building complex, this story is extremely useful in explaining the origins and history of life as we know it. Today, however, man questions non except his past, but also his future. Based on Darwins theories of evolution, man lavatory actively postulate his existence in the upcoming centuries. Do complex civilizations and advancing technologies give man the ability to outsmart evolution? Or will our technological advances doom us in the end? In order to begin to answer these questions, it is important to understand the basics about Darwins theories on evol ution. First, Darwin stressed that populations and organisms are variable (Darwin, 1859). Without athletics, evolution would not be a viable explanation for the progress of life. Although Darwin was aware that mutation occurred because of his extensive observations of different populations, he was never able to pinpoint where this variation came from. The answer lies in genetic material heritable genes play a huge role in the evolutionary process. Genes are the medium by with(predicate) which variation is passed down through generations and can be affected by several different forces. Mutation, gene flow, genetic drift, non-random mating, and genetic recombination are all ways in which genes can be altered within a population (Mayr, 2001). Darwin understood that organisms are variable, but for a long era he lacked a mechanism, or a driving force, of evolution. cancel selection, or a complex natural process of elimination, turned out to be one of Darwins most ingeniou s contributions to evolutionary thought (Mayr, 2001). Natural selection is the process by which genetic variation is sorted through and selected for through the organisms ability to hold water. Selection may be due to environmental conditions, competition with other species, or reproductive success. Those organisms that survive can then go on to reproduce, and their offspring then go for the successful traits.
