Darwins Theory of Evolution

One of the most recognized scientist related to evolution is Charles Darwin. Everyone is familiar with his studies known as "Darwin's Theory of Evolution." This basically says that all life is related and has descended from a common ancestor, the birds and the bananas, the fishes and the flowers-- all related. Basically he is trying to say that there is some sort of genetic modification over time that completely changes an organism to something completely different, keeping some similar characteristics and traits. Part of Darwin's contribution to the idea of evolutions was another theory called "Natural Selection." Natural selection is the theory that species would develop advantageous genetic mutations. The species would gain some sort of new feature so to speak over time, flying, or being able to hold breathe under water. The species would then use these traits and eventually pass it down to there offspring. The species that did not get any of these features would eventually die out and the ultimate one would stay.

Another position Darwin has taken is that Evolution is a slow gradual process, it is not something you see suddenly. In order for his theory to be true he says that "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." A complex system like this would be something like a irreducibly complex system. For example a mouse trap has 5 components if one is missing that it can not function. So darwin says unless you can find an organ like this that existed without any possibilty of modifications he will retract his theory(so to speak obviously)
