ANTH 111 Lecture 5: Jan 22 - Anthro111
Document Summary
Long term genetic markers do exist, but do not always correlate with phenotypes. Variation in skin colour for protection against uv radiation (harsh sunlight) darker skin closer to equator. Race historically defined by biological / physical characteristics. Physical variations in humans have no meaning greater genetic diversity within racial groups than in between them. Race is a discredited concept in biology and anthropology. Intelligence is a result of environmental and genetic (not different for different races ) factors. Niche construction humans changing aspects of their environment. Slash and burn agriculture created more stagnant puddles increased breeding of mosquitos. Transition from hunter/gatherers to farmers is the most profound changes in human history. Created higher levels of infection diseases associated with animals and farming. Macroevolution evolution over long periods of time leads to creation of new species. Phylogenetic tree shows evolutionary relationships as determined by evolutionary systemat- ics. Traditional view no close relationship between animal classes birds/mammals/reptiles.
