Part 3/6:
While cultural and societal shifts are evident, the question of biological evolution during this period is less straightforward. Ten to twelve thousand years is a relatively short span in evolutionary terms, making significant biological changes less likely to have occurred. Nevertheless, some adaptations have taken place. For example:
Lactose Tolerance: Certain populations developed the ability to digest lactose into adulthood, a trait linked to dairy farming.
Disease Resistance: Over time, humans have evolved some resistance to infectious diseases, particularly those prevalent in densely populated communities.
However, these adaptations are specific and relatively limited compared to the vast cultural changes we've experienced.
