In the second part of Faust Proteus gives advice to Homunculus how to be born in this world :
In the ocean deep you must appear! There, first, in miniature, one snatches, Enjoying the smallest things to swallow, Bigger and bigger, with what one catches, Forming the higher being to follow. ?
Two points:
Also I haven't read Faust but is the suggestion here even about inheritance or evolutionary change? Or is it just that one creature, in its own lifetime, gets bigger by devouring, thereby becoming "the higher being to follow"?
