9 August 2021 - evolving smarts
< yesterday --

If I’m not a space alien, you ought to ask, then how did I get to be so
smart? It comes down to the evolution of intelligence. A brain is
expensive, and has to pay for itself in evolutionary terms. It’s easier
for a social species, because you can learn from each other. But if you
have the large population to build up a large cultural knowledgebase,
then you are already successful, and more brain doesn’t pay. Genus Homo
had small populations for nearly its entire existence--archaeology and
the anthropic principle agree, fortunately for archaeology--then had a
sudden breakthrough. The small population into sudden breakthrough
pattern is a bottleneck requirement that makes it hard for a
civilization-building species to evolve. Now look at me. I’m not social
and I have a population of one, so I have to be a supergenius just to
be here. That’s why I’m your king of the world, not building
civilization but destroying.
clue:
When agriculture first started up, human brains got smaller. We--I mean,
you are probably not as smart as your early forebears. I think it’s
because farmers don’t live as well, but another theory is that farmers
don’t gain as much from being smart so brains evolve to be smaller.
That said, my argument has... gaps, you might politely say. Though there
is something to it.
give me a clue so sweet and true
