The Future of Human Evolution Alexander R. Prof. Kohn Darwinism and Evolution 12-6-96 Evolution, the science of how populations of living organisms change over time in response to their environment, is the central unifying theme in biology today. Evolution was first explored in its semi-modern form in Charles Darwin s 1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong argument for evolution. He postulated that all species have a common ancestor from which they are descended. As populations of species moved into new habitats and new parts of the world, they faced different environmental conditions. Over time, these populations accumulated modifications, or adaptations, that allowed†¦show more content†¦The first step in understand evolution in present terms is to mention genetic engineering (including genetic drift). The first step to understanding genetic engineering, and embracing its possibilities for society, is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependent on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of natures evolutionary process when an Austrian monk named Gregor Mendel developed the first laws of heredity. Using these laws, scientists studied the characteristics of organisms for most of the next one hundred years following Mendels discovery. These early studies concluded that each organism has two sets of character determinants, or genes (Stableford 16). For instance, in regards to eye color, a child could receive one set of genes from his father that were encoded one blue, and the other brown. The same child could al so receive two brown genes from his mother. The conclusion for this inheritance would be the child has a three in four chance of having brown eyes, and a one in three chance of having blue eyes (Stableford 16). Genes are transmitted through chromosomes which reside in the nucleus of every living organisms cells. Each chromosome is made up of fine strands of deoxyribonucleic acids, or DNA.

Evolution is the process of inheriting traits through DNA over successful generations. Charles Darwin, a naturalist and geologist synthesized a theory later known as Darwinism, which explains that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual s ability to compete, survive, and reproduce (Darwin, 1859). Humans haveRead MoreNatural Selection Theories Of Human Evolution1710 Words   |  7 PagesIntroduction Evolution refers to the process where living things’ behavioural and physical characteristics change over a particularly long period. As a theory first formulated by Charles Darwin in 1859, he explains the process of change that organisms go through in order to survive and better adapt to the areas they live in. Charles Darwin s theory has been widely accepted now, but it hasn t steered away from controversy particularly with regards to religion and the opposing perspective it putsRead MoreAre Humans Still Evolving?1556 Words   |  7 PagesAbstract evolution has occurred in humans for millions of years; however, in a modern society many scientists and evolutionists are now debating whether or not it is still occurring, and if it follows the same rules. With all of the new technology humans have created, some experts believe that humans have essentially conquered nature, and no further evolutionary changes will occur. Still, others hold opposing views; some experts believe th at evolution is still occurring, but modern societal advancementsRead MoreThe Evolution of Humans Essay578 Words   |  3 PagesThe Evolution of Humans The evolution of humans was (and is) a very important time. The first being of evolution was Australopithecus Afarensis or â€Å"Lucy†. Then we moved on to Homo erectus and Homo Neanderthal. When the weather got hotter, we were Homo Sapiens Sapiens and finally, the modern man. This evolution did not happen overnight. It took millions of years. The past is hardly forgotten, but the imminent is next. The future of evolution is being studied as well as the past. Most people wereRead MoreThe Evolution Of Physical Anthropology Essay1282 Words   |  6 PagesDefine evolution Evolution refers to change over time as species modifies and separate to produce several offspring species. 2) Define physical anthropology Physical anthropology is concerned with the evolution of humans, their origin, diversity, as well as adaptations to environmental stresses. Discuss some of the general ways physical anthropologists investigate evolution Physical anthropologists investigate evolution through various ways in order to give a well understanding of human evolutionRead MoreThe Fall Creek Hydroelectric Facility1671 Words   |  7 Pages1. The Fall Creek hydroelectric facility and the Cornell water treatment facility serve as two examples of human activity’s impact on core processes. The core processes altered by both facilities include the ecological, physical, and chemical processes. The Fall Creek hydroelectric facility has, by its very existence, altered the landscape of the area surrounding its main dam, most notably, its creation of Beebe Lake. The formation of the facility’s dam has also impacted the physical and chemicalRead MoreHow Charles Darwin Changed the World Forever1409 Words   |  6 Pagesas today and for future generations of the world to come. He showed that humans were created by chance and would change the world looked at life forever. Charles Darwin had a significantly great impact on culture, writing, and religion by showing the world that we are no longer God’s gift, things happened through probability, and the bible is not a book history. Charles showed the world that we were no longer God’s gift to the earth by showing that we were created through evolution and not placedRead MoreAn Investigation Into The Effect Of Immunisation On Evolution Essay1134 Words   |  5 Pages2015 Biology 1.2 An Investigation into the Effect of Immunisation on Evolution Question: Is immunisation effecting the continued evolution of our species? The aforesaid idea is not an unusual one, although it hasn’t been around for very long it has had some thorough research done surrounding it. They say that vaccines and immunisation have been helping us so much that they have started to impede upon the evolution of humans as a species. This is believed to be a valid point as, with vaccines itRead MoreDarwin s Theory Of Evolution859 Words   |  4 Pagesthat Darwin’s theory has many holes the scientists are unable to fill.

Craig Belanger works for EBSCO Publishing he stated in his Biography of Charles Darwin, which was found on the TRC database under Book Collection Nonfiction: High School Edition Belanger said that, Although there are many facets to Darwin s theory of evolution by natural selection, at its core is the idea that a species ability to evolve is based on its natural selection
