ANTH 350 Lecture Notes - Lecture 18: Adh1B, Passive Immunity, Evaporative Cooler
Document Summary
Climate adaptions and class presentations: correlations with climate: bergmann and allen"s rule. Bergmann"s rule: within species, populations have smaller body sizes and more linear body shape in hot climates and larger body size and less linear body shape in cold climates--- easier to lose heat. Really looks at body volume to surface area: allen"s rule: Longer legs and arms in hot climates, shorter, stockier in cold climates: adaptions to climate. Inactivity: recent changes in nutrition changes body shape/size. Has to do with neolithic domestication of rice. Effects individuals of east asian origin the most 36: epigenetics. Comprised of all chemical compounds that have been added/attached around entirety of an individuals dna. Epigenome use methyl marks protein that attaches directly to dna base pair to turn genes. Parents with ptsd more likely to develop anxiety disorders. Holocaust survivors have lower methylation and therefore low cortisone. Low cortisone associated with vulnerability to anxiety and psychiatric disorders: human animal disease transfer.
