It is an interesting subject. Several years ago there was some research on increased dexterity of the thumb in young people, specifically armed services recruits. You do understand that the bony spikes or nimble thumbs are not heritable.

I found this article - pop science:

Finger tapping rates as a function of age, a fairly current take on finger dexterity, I think:

This is key. Worth highlighting.

i.e it's not a genetic evolution, any more than developing a hammer toe from wearing tight shoes.
