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.
You wake in the night with your arm hanging over the side of your bed. It is still dark, and your bedroom is shrouded in deep shadow. Something unseen seizes your hand.
You grasp it tightly, knowing that first impressions are important and a firm, confident handshake will establish dominance.
