Document Summary
Matrilocality and patrilocality variation and genetic differences. Females are moving and constantly moving population females come from multiple locations to one particular location. Genetic differentiation graph: (you are considering the differences in genes measuring diversity) Further apart geographically, there is no trend for autosomes. Y chromosome greater difference the farther that they are. * female migration so the y chromosome between population greater. Human agricultural co-evolution: this is co-evolution: natural selection imposed by our agricultural practices and leaves imprint in our genome. Reciprocal evolution one imposes selection on the other. The evolutionary response imposes selection on the opposite species. Reciprocal response in our evolution and agricultural species. The species that we use for our agricultural purposes. How do we as humans co-evolve with our agricultural species: evolution occurs by natural selection, ecology is our culture and the organisms that we interact with, genetics provides the information that is transmitted through evolution. Culture does include diet, choosing a partner, etc .
