From the same population as the first two. Could you be a bit more specific as to what exactly you're trying to learn about here?
Just posting the obvious Ichy..
If the 3rd human didn't come from the first two..
then current biology must be re-written..
And if there WERE the first two.. where did the 2nd and 1st come from.?. Obviously there had to be the first three.. else where did all the others(us) come from..
There are many stories in the big city, evolution is just one of them.. and the bible too.. Humans are suckers for a good story, always have been.. Wonder when story telling was born.?. Maybe the 3rd human invented it..
The evolution of story telling... NOW theres a good subject..
Evolution(most versions of it) is a fairy tale for adults...
The Bible is a fairy tale for children..
Qu'ran is a fairy tale for morons..
it goes on and on..
Guess "GOD" just made ((ME)) a critic of good story telling..
I like a good story, HEY, I'm human..
