Natural Selection And Human Evolution - 1198 Words

Biological Anthropology Biological anthropology, also known as physical anthropology, is the study of human evolution defined by Anthropology Professor Dr. Craig Palmer at the University of Missouri. Evolution is the changed caused by natural selection. The effect of the inheritable elements on their own frequency in succeeding generations. (Inheritable elements replaced the words generations). The variation within species and reproductive success are the basis of natural selection. Natural selection was developed by nineteenth-century British naturalists Charles Robert Darwin (1809–1882) and Alfred Russel Wallace (1823–1913). Both Darwin and argued that certain individuals in a species maybe born with particular characteristics or traits that enable them to survive better. Modern scientists believe that new species emerge when small populations become isolated from the parent group and encounter new selective pressures that may favor different characteristics. Natural selection is currently viewed as one of four major forces in the evolution of species. Natural selection enabled Darwin to explain the mechanisms of biological evolution, and it remains a powerful explanation for the development of living species of plants and animals. Examples of natural selection are Hominds and Australopithecus. Hominds are the family of primates that includes the direct ancestors of humans, share certain subtle features in their teeth, jaws, and brain. Australopithecus are an extinctShow MoreRelatedNatural 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 MoreHow Organisms Evolved From a Common Ancestors1101 Words   |  5 Pagesof evolution. This theory states, â€Å"that all living organisms have evolved from a common ancestor through natural selection acting on hereditary variation† (Reece, 2011). Many people today, know humans have evolved from a common ancestor; but they do not recognize the importance of it. Everyone should be educated about how organisms evolved because humans have evolved throughout many centuries. Charles Darwin had many theories that incorporated the main principle of biology, natural selection andRead MoreEssay about Evolution1502 Words   |  7 Pagesevolutionary process: natural selection. Natural selection gives insight in to why organisms are the way that they are. Adaptations are phenotypic variants that result in the highest fitness among a specified set of variants in a given environment. In reference to humans, there are many traits that have been selected and adapted for throughout their evolutionary history giving them the characteristics that they have today. In this paper I will discuss some parts of the human body, which have beenRead MoreEvolution Is The Biological Ideal For The History Of Life On Earth814 Words   |  4 PagesHonors Biology Kohli December 14th, 2014 Evolution Evolution is the biological ideal for the history of life on Earth. (Evolution fact and theory). It is the process by which an organism becomes more refined over time and in response to its environment. Evolution is about how we evolved; how Neanderthals and cave men evolved into Homo sapiens much like what we are today. It’s about how creatures evolved over time, dinosaurs becoming extinct through natural selection and how sharks have been alive for overRead MoreCharles Darwin s Theory Of Evolution1173 Words   |  5 Pagesbelieving. Evolutionary theories were first proposed by Charles Darwin in the 19th century, and 150 years later, these ideas are still being studied and proven today. Charles Darwin set the basis for these discoveries. Natural Selection and survival of the fittest are two examples of evolution. Charles Darwin once exclaimed, â€Å"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most a daptable to change.† This and many accusations have setRead MoreReconciling Darwins Theory of Natural Selection and Intelligent Design835 Words   |  4 PagesNatural selection is an important component of evolution. Natural selection occurs when some members of a population are better fit for survival and reproduction than the others in that population (Phelan 284-85, 2011). The environment in which organisms live plays a part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longerRead 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 cre ated, some experts believe that humans have essentially conquered nature, and no further evolutionary changes will occur. Still, others hold opposing views; some experts believe that evolution is still occurring, but modern societal advancementsRead MoreEvolution Of Natural Selection Evolution1005 Words   |  5 PagesNatural Selection-Evolution Natural selection is the evolutionary process through which factors in the environment exert pressure, favoring some individuals over others to produce the next generation. Charles Darwin (1809-1882) formulated this theory that has stood the test of time. Natural selection is important to anthropology for understanding how species change. Anthropologists emphasize the complexity of evolution and how natural selection is much more than â€Å"survival of the fittest.† CharlesRead MoreDarwin s Theory Of Evolution1115 Words   |  5 Pagesbelieve is the forth coming of evolution or what they deem to be the reasoning behind its development. However, Charles Darwin would change the theories of evolution and would go down in history as one of the greatest influential figures in human existence. Although some scientist disagree with Darwin’s Theory, Darwin is the only person who was able to provide sufficient evidence to prove his theory of evolution. The one question that remains, Can God and evolution co-exist? Darwin’s Education andRead MoreEvolution Is Result Of Natural Selection1300 Words   |  6 PagesEvolution is the change in the different types of living organisms which is slow process. Natural Selection is a battle between individuals within species, which results in the survival of those organisms that are better suited to their environment than others. Natural Selection is a mechanism of evolution. There are three conditions of Natural Selection which should meet to be able to survive and reproduce, so they can pass the traits to the next generation. In all species, there are huge numbers
