Document Summary
Emphasizes important of adaption, reproduction, and survival of the fittest in shaping behavior: david buss influential in explaining human behavior, says just how evolution shapes our physical features it influences how we make decisions/aggressiveness/fears/mating pattern. Evaluating evolutionary psychology natural selection isn"t best way to study as it takes too much time, easier to study genes and their links to traits & behaviors. The collaborative gene only have about 20,500 genes in the human body. Sequence of nucleotide bases determine our genetic code, genes are the units of hereditary info (short pieces of dna) & do not act independently: cell nucleus chromosomes dna gene, human genome has genes that collab with both each other & non-genetic factors. Genetic principles: dominant-recessive genes one gene of a pair overrides the potential influence of the other, only show recessive gene if a dominant gene is not present. Beckwith-wiedemann: polygenic inheritance most characteristics are determined by many genes, cancer and diabetes are consequences of this.
