Document Summary
Evolution: idea that species and all living things we see today are descendants of ancestral species. Species as perfect and permanent: judeo-christian. Species were individually designs by divine creator. Illustrate that species no longer seen today were once on this earth. Lamarck (looked at how things evolved: body parts that are not used, traits will be changed and then passed off to its offspring. Adaptation: descent with modification , as species move into various environments, they acquire and collect a variety of modifications, end goal is to fit into the environment. Artificial selection: picking and breeding with desired trait over many generation. Natural selection: genotypic characteristics that are better suited to an environment is more likely survive and reproduce, thus increasing the traits frequency and increasing the species chance for survival. Traits that can better tolerate harsher conditions have a higher percentage of passing on the trait. Traits can only be amplified or diminishes.
