Document Summary
Natural selection: mathematical formulations proving how environment chose certain organisms to live on. Environmental variation: variation among individuals due to di erences in the environment. Genetic variation: genetic material transmitted from parents to o spring. Mutations arrive from random errors during dna replication or from environmental factors. If not corrected they pass onto the next generation. Evolution is when genetic makeup or a population changes over time. New species arise by divergence of population through timefrom a common ancestor. Humans and chimps share more features than they do with other species. Evolution theory predicts primates should show a nested pattern of similarity. Three major branches in life mostly made of microorganisms. Tree of life makes predictions for order of appearance. Both are subject to basic laws of chemistry and physics. Chemical emleents that make up living things can be found in non living things. Relative abundances is what changes and is di erent.
