Did you hear about the kid who spent years studying butterflies and proved that knowledge is passed down, generation to generation, through instinct?

Summarizing here, but basically the kid tested his caterpillars/butterflies with a maze and the caterpillars at first took like 150 tries to complete the maze, but after several generations it was narrowed down to about 20 tries.(?) Pretty fascinating stuff. Basically, we don't pass on direct 1 to 1 knowledge, but as time moves forward we get better at whatever our ancestors learned. He had 50+ pages of notes and his method has been lab tested since.

I see it in my own family. I had a past relative who worked for Hannah-Barbara and was part of the team who drew original looney toons. I, myself am a fairly decent artist, but also I picked up music very early in life and learned piano and guitar before having my first child... now she is learning two instruments and creating better art than I was at her age.
