Document Summary
With these 3 observable facts, he was able to come up with natural selection". Ex: white bunny living in snow will live longer bc able to blend in, thus there"ll be many bunnies produced. Depending on traits, organisms able to live either longer to survive. Parents less likely to survive, less likely to produce offspring. Less advantageous traits won"t be passed on. Each gen, there"s going to be selective factors of the environment (constantly changing thus traits need to change in order for the animals to survive longer/better) Natural selection = always working at level of the ind: ind animals survive or don"t, so ns is always working at the ind level. Evolution = working on the entire population level. These show the diff units of evolution. Every generation = resetting depending on whether organisms well suited to environment or not. Mutation cause change in the moths (became black) this way they stood out a lot more than before.
