Crows Quote by Jennifer Ackerman
““Did the crows’ bill shape and specialized vision predispose them to tool crafting and use? Or did their tool-use behavior in response to unusual ecological opportunity—those delicious hidden grubs—gradually shape their visual system and bills? This is the sort of mysterious causal relationship biologists both love and hate.””
