Document Summary
Natural selection is the outcome of certain conditions being met: variation. If something whipped out that trait: heredity. Why is it important: favorable traits from the parents are passed down, why need inheritance? b. i. Trait is more likely to die off b. ii. Will have to start all over again: competition. Why is it important: resources (but what if there was unlimited) a. i. Not all organisms would be able to grown fully. Result: evolution by natural selection, in a natural population. Natural selection for differential reproductive success: constraints. History (lineage) can strain the kind of changes that can happen. Consequences: evolution, adaptation, change in environment effects the adaptation. Genetic modification over taken by humans combining the genes they see fit. Play with genome of organism and manipulate it the way we want. Phenotypes: the outer look of the animal: dogs: came from wolves, now big and smalls breeds, pit bull, pomeranian.
