The more I read about genetics, the more I believe that God didn’t need to follow human genetic principles. He created from scratch. Thus, Eve and Adam were individuals created as a separate step before genetics kicked in.
If God did that, then He did a very peculiar thing. He created humans with a suite of broken genes that are shared in such a way with other primates that indicate either common ancestry, or deception on God’s part. He would also have had to create humans with endogenous retroviruses, tandem repreats, and processed and unprocessed pseudo genes shared with other primates shared so that the reinforce the dichotomy - either humans share a common ancstry with chimpanzees and other primates or God is a deceiver.
Let’s look at the broken genes. Everyone knows about GULO, the gene that is part of the vitamin C synthesis process that is broken in exactly the same way in apes and old world monkeys, but is functional across the rest of the animal kingdom (actually it is also broken in guinea pigs, but in a different way). Recently David Haussler et al published a paper reporting other genes that are generally functional in other organisms but are broken in humans. (One of these of course is GULO, but they found several others)
A particularly interesting one is Acyl3, a gene that is highly conserved and which is found in archaea, bacteria, fungi, worms, flies and mammals. Except that it is broken and non-functional in humans because a mutation has inserted a stop codon in the middle of the gene. The exact same mutation is present in chimps, but the gene is functional in gorilla, mouse, rhesus, rat, dog and other mammals. So unless, we say that God deliberately created humans and chimps with the same nonsense mutation in a highly conserved gene to deceive us, then we must conclude that humans and chimps share a common ancestor, and that this gene was broken before the divergence of human chimp lineages but after the divergence of gorillas.
Here are some others:
Crygf: Broken in an identical way in human, chimp, gorilla, but not orangutan or other primates or mouse or dog
Nradd, Gsta4, Sult1d1, Pfpl: broken in an identical way in all apes but not other primates or mouse or dog
Gucy2d, Nepn, BC018465, Gm766: broken in an identical way in old world primates but not new world primates or mouse or dog

I don’t think it makes good sense to declare that “Eve and Adam were individuals created as a separate step before genetics kicked in”, (quite apart from the fact that genetics is as old as living things) unless you are also willing to conclude that God is deliberately deceptive.
