      Around the early 1800s there were 128 random strangers on Earth, each of whose genes makes up 1/128 of you. Some prob. knew each other and had no idea they'd share a common descendant. There are 127 critical sex moments in this chart. If just 1 doesn't happen you never exist. 1/5pic.twitter.com/85Zrg9DNK5

      Of course if you keep going, things quickly get hectic. In the mid-1600s, you've got over 4,000 ancestors roaming the Earth. Some of them probably fucking hated each other. Also, now you're relying on 4,095 times people banged—if only 4,094 had happened, you wouldn't exist. 2/5pic.twitter.com/fosiPVdYWJ

      Keep going with this and you reach a weird contradiction. How is this explained? "Pedigree collapse," a euphemism for a whole lot of incest. Fun fact: 80% of all people who have ever lived have been born to parents who were second cousins or closer. 3/5pic.twitter.com/aAmXL3XJmd

      Cousins gets weird too. 1st cousins share a set of grandparents. 2nd cousins share a set of great-grandparents. And so on. This number quickly balloons out, esp when people have a lot of kids. Everyone on Earth is 50th cousins or closer. We really are all one big family 4/5pic.twitter.com/WNTVDVMIQH

          That is a lot of family to disagree with.

          You can't prove that mathematically. There may be lineages so isolated or inbred that they don't fall into the super group of 50th cousins you suggest exists.

          This must be why people from every race think everyone from all other races looks the same and all us mixed kids are pretty sure just about everyone else on Earth is clinically insane. Probably, I mean. I'm only saying that it would explain quite a bit.

          Did you consider in yr equations the option of marrying multiple times between 2 families? I have a lot of cousins who have the same grandparents as I do...
