also apparently this rock art dates across multiple periods spanning thousands of years? but i couldn't find much detail on that so i can't give specifics

but yeah, this isn't just a memory of giraffes, but of giraffes now absent encountered by people just 2000 years (the difference between the late roman republic and today) out of the ice age, in a climate unfamiliar to any of the hundred billion people born since the desertification of the sahara drove the ancient egyptians to the nile, near the start of the agricultural revolution

the time between this and the birth of the sahara was nearly as long as the time between the birth of the sahara and now, in which all recorded history is contained, and all languages we can recognise at all - the language and culture of these people would be totally alien to current libyans, twice the difference between the oldest european language and english, predating all but libya's mountains!

basically, there's been an ants' nest near a vent shaft of this abandoned Soviet bunker for decades. the nest spilled over into the bunker itself at some point once it was abandoned and there was no way for the ants to make their way back up to the nest, no queen but a constant supply of new colony members raining down from above, and no source of food in the bunker other than the corpses of their fellow ants.

fast forward to some scientists looking for bats that stumble on what's basically a post-apocalyptic ant society. they go "holy fuck" start studying, and observe that, all things considered, the ants still pretty much act like regular ants doing regular ant things.

fast forward some more, and the scientists feel like they have enough data from observing the colony as-is, so they decide to try an experiment. they put a little walkway between the bunker colony and the og colony in the vent shaft so the bunker colony members have the option of leaving and rejoining the og colony.

spoiler alert: every single ant in the bunker immediately nopes the fuck back to the colony in the vent shaft. within days the bunker is completely empty. the scientists leave the walkway in place so when more ants inevitably fall back down the vent shaft they can just climb back up instead of starting up the cycle anew.
