Do you mean to say that androgen production varies adaptively across
species, reflecting different selection regimes? Or literally, that
testosterone is the main selective pressure in human evolution?
Are you aware that testosterone is immunosuppressive?

Are you suggesting that transcriptional errors are more common during
chimp development? Do you have any evidence at all for such a sweeping
statement?
