ANTH 1001 : Anth 1001 Test 2 Notes
Document Summary
Bergmann"s rule body mass increases in areas of low temps. Metabolic rate of someone at high temp low. Transferred to keratinocytes which are also in the epidermis. absorbe uk light. Human variation perspective any beneficial modification which relieves environmental stresses and enhances survival . Behaviour, genetics, long term acclimatization, short term acclimatization. Natural selective advantage for dark/tanned skin reduced risk of skin cancer. Natural selective advantage for pale skin enhanced absorption of vit d. reduced risk of rickets. High altitude acclimatizations long term increased size of right ventricle/lung capacity/chest circumference. Lactase enzyme which digests lactose (sugar in milk) Metabolic rate of someone at low terms = high. No one is the same result of environment we inhabit due to natural selection. Lactose intolerant deficiency in the production of lactase. Allen role short legs/arms are found in areas of low temps. 2 theories that characterize prinates aboreal theory early primates were adapted to life in trees grasping hand/feet.
