"If" true, then once again we see "devolution" in progress. An ancient ability was to form proteins was loss.

This is just willful blindness. It's no loss to lose the need for something upon which you cannot rely. The loss of a vulnerability to malnutrition is a gain. At any rate, there's a gain of an ability to form a new protein. The net ability to synthesize proteins is unchanged.

It certainly looks like willful blindness to me. The loss of an INvulnerability to malnutrition is a loss. Neanderthal had an INvulnerability, that we don't, so we apparently lost it.

All right, I misread it.

I thought this was related to the much touted lack of human's and guinea pig's ability to sythesize vitamin C. And therefore I assumed that Neanderthal had it and the rest of us didn't.

So if it's something Human's had all along, and we don't have any proof that human's ever lacked it. They why are we assuming that Human's EVOLVED it?
