Let’s say your matrilineal line is fairly consistent and everyone has their daughter at 25. So four women in your matrilineal line are born every hundred years. In a thousand years, that’s only 40 women. Like the math is so simple and yet ? You don’t think about it. So in 2000 years, 80 women. So basically, 0 AD started roughly about 80 mothers ago. That’s it.
