Document Summary
There is not a whole lot of variation in the genetics of people from different countries. In a test they genetic compositions grouped into 4 clusters, the largest cluster was from the. Supposedly we all originally come from the africa area which is why there is so much variation there. *cv mean coefficient of variation* the average cv is about 0. 053. About 190,000 years ago an example of a genetic bottle neck is when the humans spread out of. Out of africa model is a model of human evolution showing the dispersal of h. sapiens: neanderthalensis and h. erectus. This model shows that humans co-existed with other species like the other homo species. Homo neanderthalis lived in europe and western asia between 35000-28000 years ago. Therefore, they coexisted with humans for about 60000 years. 1 -4% of human genomes come from neanderthals. Asians and europeans are more closely related to neanderthals.
