Right, but that's not natural selection, that's mutation. Natural selection can pick up on the changes after they've taken place.
e.g., There's presumably a gene out there that makes humans twice as intelligent at absolutely zero expense, and although if it were to appear it would be selected for, it it clearly hasn't happened yet. Natural selection can't drive that to occur.
- guard-of-terra 13y agoIs there a gene already in human DNA which would make humans two times smarter if repeated / made more active? That's what happens with weed rice. Btw the answer can be yes. We are no longer constrained by food concerns but our genome does not account for that yet.
