Document Summary
Use genetic principles to understand ecological and evolutional aspects. Paternity requires genetics: possible results: null) no difference, inbreeding preference, inbreeding avoidance, result: elephants avoid their kin, also holds for paternal relatives, inbreeding depression is strong. 0=no differentiation: mtdna: 0. 28, y-chromosomes and autosomes: 0. 03. Diversity from matri/patrilocality have to do with patterns of genomes. Coupled cycle of selection and evolutionary response between species and in different sexes. Evolution by ns is a genetic and ecological process: ecology (in humans, includes culture), produces selection, genetics provides the material that is transmitted across generations. Lactase production usually declines in adulthood except for people of north. European origin: cause of lactose intolerance (wild type, wt = lactose intolerant as an adult. Changes in lactase gene is correlated w ability to digest lactose as an adult. Conclusion: strengthens inference that molecular variants affect phenotype, independent evolution in dff pops support driving force of ns.
