There seems to be plenty of messengers (such as Lacerta) who seem to suggest, that, yes, human-DNA is in fact, altered, changed, tampered, and, that, various versions of humans have existed throughout this earth's history... I will need to go back and listen to it again to get the exact number, but, I think we're on something like the fourth or maybe even seventh «installment» of humans, not just a mere human 2.0, but, human 4.0, human 7.0, perhaps human 7.1, etc. May as well re-link that interview here whilst I'm at this...
