Things About Early Humans That Will Blow Your Mind
Early Humans Had Surprisingly Low Genetic Diversity
Despite having found a large variety of different human species, the discoveries don’t differ too much in terms of their genetic make-up. The scientific reasoning lies in the fact that we (and all of our ancestors) come from the same location in East Africa, where it is assumed all of our human-ape ancestors lived. In order to determine genetic diversity, scientists need to know the effective population size of a specific group.. This size helps to understand how many organisms you need to create the genetic diversity of the full population. For our species, this number is 15,000 individuals to recreate a society of over 7 billion people.
