I recall an experiment where 30 or so people are arranged in a circle, and one starts off wispering information into the next one’s ear, and the last one tells aloud what info they recieved. It normally morphs from the initial info.
Such is the nature of mankind.
And DNA is incapable of replicating itself with 100% accuracy - thus change is inevitable. The real question isn’t IF evolution happens - it is what could possibly stop it from happening.
But what if the information wasn’t whispered, but given in front of all? And the listeners best able to remember and communicate all the information were given monetary reward and high social status?
