The four forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the

of evolution puts forward a statement‚ ‘Survival of the fittest’. This is widely considered true‚ but in reality truth is a slight variation of this‚ more commonly known as natural selection. The survivors are the ones who adapt best to their environment and are then able to reproduce. This means that there genes carry on through the generations and we gradually see the preferred characteristics for survival become more common. Over time the human race will become more and more adapted for survival

Introduction Charles Darwin (1809-1882)‚ a British naturalist‚ biologist and geologist who is known to be father of heredity and evolution. He proposed the theory that governs heredity known as theory of evolution and the process of natural selection.

Darwin’s Theory on Natural Selection Though his writing can be difficult to understand and at times boring‚ the structure is organized. His smooth and fluent style‚ helps the reader gracefully follow along. Though his findings inspired many scientists to scientifically analyze his claims‚ Darwin’s studies were not with in the realm of science. Rather‚ his findings are logical which he found by studying various species among the natural world over a long period of time. The use of constant examples

otherwise known as a naturalist. Darwin began a long voyage to explore the natural world. He collected fossils and sketched several animals. From this‚ he created the theory of evolution. A common ancestor is the most recent ancestral form or species from which two different species evolved. Evolution is certainly not something everyone agrees on. Millions of people have made theories‚ which are explanations of a part of the natural world that typically has many confirmed observations‚ laws‚ and verified

“On the Origins of Species by the Means of Natural Selection” Reprise Written by: Darwin … we‚ as a human species‚ have many unique differences‚ which are known to commonly appear in offsprings of the same parents. Through frequent observation and mutations over time‚ these unique differences are presumed to have surfaced in similar people having the same limited conditions. However‚ consideration isn’t given to the notion that all organisms of the same species are actually alike in character

Although Charles Darwin formulated his idea of natural selection at age thirty‚ he published his work years later for fear of the controversy that would overshadow his work. Darwin’s theory of natural selection challenged the normal science of the time: the belief that a divine creator created all the species‚ which were incapable of change. Darwin’s theory also challenged the overarching authority of the time: the church‚ which supported the ideology of God creating a static species. Furthermore
