Humanoids already existed (think slightly more advanced Neanderthal types). Adam and Eve were both of these, but they were changed (flash of inspiration, touch of God, random mutation, take your pick) effectively elevated them above that level. (God evolved his Pokemon. LOL) So, while they were “created” as many and woman, they had a standard mammalian birth, and thus each have a bellybutton.
Just a hypothesis, nothing more. Do with it as you will.
As an evolutionary biologist I promise you that this makes way more sense in your head than it makes in actual reality. This is not how evolution works.
My point is that it makes no sense in the framework of reality and that you might as well go with the literal story of Adam and Eve or whatever mythology you want, because throwing Neanderthals into the mix does fuck all in terms of making anything believable. It’s literally as scientifically justified as the Norse creation myth about a giant cow licking salty ice to uncover the gods.
Not claiming this is evolution. Far from it, that would happen on a much longer timescale and not affect only 2 individuals. You’re focusing on the wrong aspect of my theory.
Okay, on what aspect of your theory should I focus? There is no support for a sudden transition to “intelligence.” It’s literally all continuous to the point that people are studying the learned and taught moral rules among chimpanzee and baboon populations.
The closest thing scientifically that we’ll ever come to Adam and Eve is probably Y-chromosomal Adam and Mitochondrial Eve
