Climate Effects on Human Evolution This article explores the hypothesis that key human adaptations evolved in response to environmental instability. This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. (Illustrations for this article coming soon.)

The purpose of this experiment was to observe the process of human evolution by observing similar features of the Pan troglodytes‚ Australopithecus afarensis‚ Homo erectus‚ Gorilla gorilla‚ Australopithecus boisei and the‚ Homo neanderthalensis in comparison to those of the Homo sapien. According to Darwinism‚ the species that had the most traits in common with the Homo sapien must be the most related while species with the least traits in common with the Homo sapien were the least similar. For example

Evolution is a word that brings a wide range of emotions in people. For many‚ fingers crammed into ears and the refusal to discuss it is an act of behavior because they believe in the Biblical account of creation. Nothing more‚ nothing less. Then there are those‚ who do believes in evolution and are well versed on the matter. They become loud and boisterous to those who have their fingers crammed in their ears refusing to listen. Name calling and finger pointing comes from both sides of the firing

Should Intelligent Design be Taught Alongside Evolution A trial is currently taking place in Harrisburg‚ Pennsylvania concerning the question of whether a local school district can require students to be told about intelligent design (ID) as an alternative to Darwinian evolution (Holden 1796). This trial‚ known as Kitzmiller v. Dover Area School District‚ could result in the setting of a national precedence. The reason for this is that the losing side is likely to appeal every step of the way

not be anti-evolution laws‚ no Scopes trial‚ and no Supreme Court decision. Bryan’s attitude for evolution had three errors to it. The first error was that he made the mistake of confusing the fact of evolution with Darwin’s explanation. The second being that he misinterpreted the natural selection as a theory of survival. The final error would be that he argued that Darwin’s theory implied that moral virtuousness of deathly struggle. In Bryan’s campaign against evolution in schools‚

Lamarck’s Influence on the Development of Darwin’s Theory of Evolution Dec. 4 1996 Marc Weinstein There have been many ideas on the theory of evolution. Some simply take our existence for granted‚ others prefer to explain all evolution in terms of the bible and the presence of a God. However‚ there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been

There have been many theories that explain how evolution occurred. Charles Darwin‚ on the book Origin of Species‚ spoke about how traits are passed on from generations to generations by natural selection. In addition‚ he stated how there are four objections to the theory of natural selection‚ how species can win the struggle for existence through natural selection‚ and how the origin of species challenges religion. Central to the theory of evolution‚ is natural selection. Evolutionary theory was

natural selection‚ evolution‚ mutation‚ variation‚ heritability‚ and fitness. EVOLUTION IN ACTION Darwin envisioned natural selection acting so slowly that its effects would be imperceptible in a human lifetime. But in the late 1900s‚ evolutionary biologists began to detect small but significant changes taking place in a handful of species. In the past decade‚ many more cases of natural selection have come to light‚ and scientists now realize that species can adapt quickly to changes in their

The results of this study relate to the larger issue of how the forces of evolution work in real world populations since mutation‚ genetic drift‚ gene flow and natural selection are within species all around us. One population that experiences these four forces of evolution is a population of bears. When it comes to mutation‚ if a population of bears only had dark-colored bears‚ but then all of sudden a light bear appeared in the population this would mean that one of the alleles that determine fur

Creation versus evolution; faith versus reason. There has been an ongoing debate ever since on how man first existed. As people have been trying to unlock the mystery of life‚ many evolution theories sprang up – one of which is Charles Darwin’s Theory of Evolution. Darwin’s theory made a big impact in science and has only gained more acceptance as years went by. It was widely accepted as the explanation for the diversity of organisms‚ and there were proofs claimed to support it. But today‚ we will
