RE: Y Chromosomal Adam and Mitochondrial Eve: Polygenism and probabilistic considerations

Perhaps you don't realize that for any particular gene, we have different common ancestors.
The Y-chromosome and Mitochondrial DNA are different, because they do not undergo mitosis, and we can find a statistical point of common ancestor for each.
However, the common ancestors for each of these can be different by a hundreds thousand years! And yes, there were people existing at the time, or where did these people (or the rest of our genetic makup) come from?
We share common genes with fungi, so the common ancestors for those genes existed hundreds of millions of years ago.
