Did you know that you and I are cousins?
I find this very interesting. It is not something I was aware and it is very surprising.
What it is saying, in short, is that we are all, more or less, cousins on this planet. With every person on earth, right now, you and that person will find a common ancestor somewhere in the past. That past might not be that far, most likely a few thousand years, not a hundred thousand.
The notion of isopoint is also worth discovering.
>>> “Imagine counting all your ancestors as you trace your family tree back in time. In the nth generation before the present, your family tree has 2n slots: two for parents, four for grandparents, eight for great-grandparents, and so on. The number of slots grows exponentially. By the 33rd generation—about 800 to 1,000 years ago—you have more than eight billion of them. That is more than the number of people alive today, and it is certainly a much larger figure than the world population a millennium ago. “
