It’s hard not to see this angle as making the capacity for cultural evolution very fortunate for us (or unfortunate for other species). What other animals can exhaust primary food sources and ‘quickly’ pivot to another? I’ve often wondered how much rituals and social routines for affiliation and bonding drove for this capacity (which we often associate with lithic tools) as opposed to the need for food. Perhaps some of this is due to another scarcity: hair. How did hairless apes manage relationships without grooming?
