About 5000 years ago most humans were lactose intolerant.
Then came the rise in pastoral societies, and the gene to be able to process milk spread like wildfire.
Now I think only 5% of people in the world are lactose intolerant.
That’s a pretty big evolutionary step, very recent.
It’s called engineered adaptability.
The pre-designed DNA information was turned on in response to environmental (dietary) changes.
No evolution.
No new information in the genome.
Engineered adaptability.
