Although I like these evolution arguments purely for entertainment value,
As far a science is concerned, I can shrug my shoulders and say we are only discovering what God already made, and leave it at that.
We are unlocking the mysteries of our biological nature and are at a point now where we can manipulate it, perhaps to our own undoing if we don't proceed with extreme caution.
The potential to unlock a biological disaster is very real. We've already seen the potential danger of how a mutation can cross the species barrier and have the potential to wipe out all those susceptible to that DNA sequence (prionic diseases).
We have to be careful.
And very wise.
And very, very lucky.
