And actually it’s completely stupid. Love that in the USA this is possible.

It’s great that’s it’s actually possible. In many soccer stadiums he would not have even survived getting to his seat in a shirt of the other team.

Time to actually start writing more effective code and efficient hardware use.

Yes, as I state in my post other DNA might still be mixed in into the lines. As the egg organelles come from eve, there might be much different dna in the chromosomes.

Same for the male thing.

Actually there’s many humans with Neanderthal and Denisova dna. Interbreeding took place and introduced different dna.

In the end we all descend from just a few women (mitochondrial eve)

And a handful of men (y-chromosomal Adam)

There was a period humans were almost extinct and of those only a few people are responsible for all of our genetic material.

Even so: mitochondrial dna might come from ‘eve’ , some of the other humans or even humanoids (like Neanderthals) might have given us part of their dna by breeding. It’s just mixed into the y- or mitochondrial lines.

Still there are many factors of which I know only a few. Must important would be distance / travel. Micronesian people might share a Europe’s and African forefather, but after they separated ages ago they didn’t breed back in. Same for native Americans or Australian natives.

Still it’s very interesting to see there’s still a lot of things being found out. For instance that denisova man interbred with early humans and Neanderthals and many Asian people have some denisova dna and Europeans/Caucasian have up to 5% Neanderthal dna.
