A knockdown prophecy

[HappySkeptic]

Although that's part of the mentioned hadith, it's another topic entirely. Suffice it to say that there is necessarily a first human. Even without any knowledge of evolution or biology, we can declare with 100% confidence that there is a first male we label Adam.

No, there isn't.  Evolution doesn't work that way.  One could always say "modern humans have gene ABC, and pre-humans didn't", but then you would probably find some modern humans that don't have gen ABC either, and that gene might end up being found in some ancient hominids in some degree.

Also the idea of a common male chromosome-Y ancestor, seems reasonable, but that isn't all your genes!  Every gene in your body has a different common ancestor, and some go back to the time of bacteria.  The common female mitochondrial ancestor isn't even a common ancestor of any of your genes, but of a symbiote. Plus, the common ancestor of these just means the other lines died out, not that they weren't equivalent or in any way substantially different.

There is therefore no first male or first female human.
