Natural Selection Theories Of Human Evolution - 1710 Words

Introduction 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 puts across. Despite the backlash and attacks, the theory provided the basis for a lot of research and insight into evolution, and the amount of evidence available today is impossible to acknowledge (Costa 2009 p. 890). It has been shown by numerous†¦show more content†¦Over many years, the population will have organisms that have adapted to the areas they are living in. This concept of natural selection is actively taking place in humans of the world today and will affect Homo sapiens of the fu ture. Researchers, in a very detailed study, used thirty-nine people and a chimpanzee, a close relative of humans, to analyze the genetic makeup. It was not a surprise to discover that rapid evolution is still going on as evidenced by the studies; up to nine percent of the genes were changing. In another study, it was discovered that the brain of humans is also undergoing evolution. Past Evidence of Human Evolution Over the years a lot of studies have been carried out with regards to human evolution making available a great deal of information that proves that humans indeed evolved over millions of years. The many fossils found (in their thousands) have enabled students and researchers to delve into the early human life and the various aspects that kept changing over the years such as diet, locomotion, body size and the brain. Evidence shows that humans have been existence for over six million years (YANG, LU and GU 2013, p. 243). Human behaviour can be traced from the millions of footprints, paintings and figurines, and tools of stone that have been discovered. This evidence can enable researchers to know the innovations in technology made by the early humans and how andShow MoreRelatedHow 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 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 Pages It is time to start believing. 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 adaptable to change.† ThisRead MoreDarwin s Theory Of Evolution1115 Words   |  5 Pages There are many theories as to what scientist believe 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 GodRead MoreEssay about Evolution1502 Words   |  7 Pagesthat equip them for survival and reproduction, Darwin (and Wallace) independently came up with the central theory of evolutionary 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 givingRead MoreBelieving in Evolution Essay1171 Words   |  5 PagesBelieving in Evolution Darwin did two things; He showed that evolution was a fact contradicting literal interpretations of Scriptural legends of creation and that its cause, natural selection, was automatic with no room for Divine Guidance or Design.

It â€Å"is the process by which modern organisms have descended from ancient ancestors† [1]. Many great scientists have developed theories to answer the question, â€Å"Where did life, and human beings, come from?† Two major theories of evolution that still exist, and valid today are Charles Darwin’s theory, and Lamarck’s theory. These two theories have many differences, but attempt to explain evolution. Charles Robert Darwin, was a naturalist, who proposed one of the most renowned theoriesRead MoreEssay on The Validity of the Theory of Evolution1539 Words   |  7 PagesSince the publication of Charles Darwin’s Origin of Species, in which the theory of evolution has risen, people have debated the merits of the theories of creationism and evolution.

According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title On the Origin of Species 1859†. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmentalRead MoreWhat Is The Evidence For Evolution?1363 Words   |  6 PagesWhat is the evidence for evolution?
