Document Summary
5 major points of darwin"s natural selection: more creatures born that can survive, there are variations in traits, some traits are more advantageous, advantageous traits have a better change of survival & reproduce, disadvantage traits are destroyed. Evolution: the change of organism due to a difference in genetic variation to adapt to the changing environment. Evolution can"t change a person gene after they"re born. You can"t change traits over your own lifetime. If you carry that favored gene, it will be passed down onto your children, changing generations after. Variation is important to natural selection b/c its variation that triggers evolution. variations offer difference b/t creatures that allow them to have ability to survive in environment. If no variation, then they will either all be favored, or not favored, leading to no population or a great population that wont withstand anything that happens in nature,
