Look, I just gave you real world examples why and how your view on evolution is undercomplex and wrong, also I did explicitly tell you there’s more to society than the pure basics of evolution.

Maybe – just a really wild speculation here – the adult Gorns are responsible for the Gorns being a space-faring species, like, you know, the same way humans don’t need school and university for survival…

What is reading

It’s also a lifestyle that selects for intelligence (small hunters tend to be pretty smart)

Humans are already on the large side for mammals and are pretty intelligent (or let’s rather say successful)

Why would there be a species where the adults are intelligent and social enough to be a spacefaring power, and yet apparently nothing they learn as an adult is needed for an individual to pass on it’s genes?

You already do know another species who does that, and you call those useless adults Nana and Gramps.

There’s more to a society (and to evolution) than just surviving and procreating, you need knowledge and history. This you can only build when you’re not constantly fighting for the very survival, so having people around who aren’t busy with procreating all the time is actually the most likely route to developing genuine sapience.

Because it’s way more precise than pouring liquids into a beaker (which can be off by 10%), much easier to judge than bending down to judge a level, and since with water 1 ml == 1g (yeah, metric system helps…) fairly easy to calculate. All other liquids commonly used are close enough.

Also what the fuck is 3 cups of flour/rice/salad (?!) even supposed to mean. Loosely packed? Compressed?
