Document Summary
A bottleneck event in human evolutionary history. Gene flow between different human populations due to migration. A group of populations sharing certain characteristics that make them distinct from other groups of populations. 85% of variation is accounted for by individual differences within populations. 10% of human diversity is accounted for by different geographic regions. 5% among local populations within geographic regions. Would draw conclusions about other races from second hand information. Beliefs and/or practices that aim to improve the genetic quality of human populations. Moved from study of race to the study of culture. People tend to choose their mates among those they live close to. The relationship between geographic and genetic proximity reflects gene flow. Is continuous and thus cannot be classified into categories. Some types are more common in some regions. Relaxed selection on dark skin and direct selection to absorb more uv to make vitamin d.
