Continuing with the model of doubling our ancestors each generation that we go back, presents an inherent anomaly because we end up - just by going back two thousand years with a million trillion people in our immediate ancestry. That, is said to be more than the number of people who ever lived. So there must be a logical explanation.
The pyramid model means that two uniquely unrelated people came together to parent the next generation. However, a rather different model may show that two parents of one of our ancestors might not have been so distantly related and therefore there may be overlap. An individual may have cousin-parents and thus six great-grandparents rather than eight. Before the time of mass travel when people lived in small villages, individual genes came often from a tight pool .
Expand that out and people begin to connect with one another very rapidly. I think this says something very important about people in general and this challenges ideas of genetic diversity supposedly used to present ideas of superiority and racial separateness. If our ancestors were related then so are we and today we're all very much part of a continuing human web. There are plenty of overlaps and whatever our race and ethnicity, ultimately of course, we all go back to the same source.
