@Toni_Torppa if you want to get a little more of an appreciation of how genetic diversity confirms an African origin of humanity and mutations as the cause of genetic diversity rather than “created heterozygosity”, independent of the validity of Jeanson’s claims about unrooted trees and mutation rates, I’ll reccomend that you read the first point of evidence, titled “Ancestral Alleles” from another one of my blog posts:
Again, it’s true that I’m not an expert in this field, but I have at least completed multiple graduate courses in population genomics, which is more than Jeanson can claim. If you take Jeanson as an authority on, well, any of the subjects of the “papers” he’s published in ARJ, you should take me as an authority on this.
