Mini-Project #6. Darwin's Evolution Theory.

What is Evolution? "Evolution is a change in the gene pool of a population over time .A gene is a hereditary unit that can be passed on unaltered for many generations. The gene pool is the set of all genes in a species or population".

The theory evolution by means of natural selection (which was Charles Darwin's theory) has been shown to be the best explanation for the path evolution has taken life. The hypotesis of how natural selection works are frenquently modified and challenged as we learn more every day of our world.

Dawin's theory is called the theory of evolution by natural selection. Darwin's theory of natural selection was based in different things. First, that organisms increase more rapidly than their food supply. Due to limited resources, all life forms struggle to survive, but only the superior ones survive. Those individuals that possess some characteristic that is useful in adapting to the environment increase their chances of survival, and produce more offspring with the favorable characteristic and pass them to the next generations
