Document Summary
Natural selection: darwin & wallace theory of evolution by natural selection, all species related by common ancestry, all species can change over generations, heritable variation leads to differential reproductive success, variation, heritable, influences fitness, artificial selection, humans drive evolution, repetition leads to altered characteristics (domestic pop, dogs size / corn kernels / cows production / brassica oleracea, graphically phenotype shifts over time, speed. Taxonomic levels: kingdom, phylum, class, order, family, genus, species, molecular variation in nucleotides infer relationships, dna similarity signifies relation, new taxonomic levels domains, bacteria, archaea, eukarya only one with nucleus, node common ancestor, 1st node luca. Myths: evolution is not goal directed, adaptations do not occur because animals want/need it, evolution does not produce a hierarchy, all species evolved from luca none are higher, evolution does not increase complexity, genome size not correlated with complexity, animals do not act for the good of their species, kin selection.
