Genetic Origins

Humans migrate quickly and our rate of gene flow between populations is much higher than between populations of great apes. Gene flow decreases diversity and genetically homogenizes a species, our species is a great case example of that effect…of the 3 billion base pairs in the human genome, there are 38 million variants of difference within our species… most variants appear in only one or two people or populations. Founder effect dictates degrees of human genetic diversity within our species. Genetic Origins.
