ANT 2511 Lecture Notes - Lecture 17: San People, Macroevolution, Mutation
Document Summary
Macroevolution the study of evolutionary phenomena that causes one species to change into another species. Evolution change in gene frequencies in a population over time. The very high frequency of blood type o in native americans is the result of what? founder effect. If a child dies as a result of recieving two recessive alleles from the parents it"s an example of what? selection against a recessive allele. Hybrids due to cross-breeding is an example of what? gene flow. What evolutionary force would increase variation between populations? genetic drift. What causes malaria? a parasite carried by mosquitoes. Punctuated equilirbrium alternating periods of stasis and rapid change (niles and gould) Why are humans tall and thin if they live in hot and dry environments? high surface area to volume ratio helps radiate heat. Method of heat loss for humans? evaporation through sweat. Acclimation genetic changes that can not be inherited.
