"Crows are currently experiencing their stone age, but we will never see cool modern crows because we will be long gone before they reach the next stage.
Basically they have been creating tools which researchers are saying are actually more advanced than ones that early humans made. They also have been studied domesticating wolves! They hunt with them, sleep with them, and individual crows have been seen specifically bonding with individual dogs, like humans do with pets."
the same way 85% of stats are figured.
BTW, Weedle s#cks @$$ in general as a Pokemon, as does its evolutions, so the fact that it can't learn anything "fancy", is not a problem. DO NOT waste your in-game time trying to get a great Weedle, FFS.
