It's the dunk tank.

This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.

Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.

Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.

Rule 3: No sectarianism.

Rule 4: TERF/SWERFs Not Welcome

Rule 5: No ableism of any kind (that includes stuff like libt*rd)

Rule 6: Do not post fellow hexbears.

Rule 7: Do not individually target other instances' admins or moderators.

Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this.

Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

In fairness. Humans did specifically massively increase brain and skull size to fit all our smarts in, no?

On a time scale of millions of years, yes. Not in the last few decades. This is an insane thing to say.

Genetic determinists think that a couple generations of PMC people marrying other PMC people will produce a new subspecies or some shit. Like bruv even ignoring how that's not really happening the way you think it is it takes a lot more than that.

What's PMC mean comrade? Help those of us with smaller heads

No, that's a hold-over from the caliper people

One group of researchers has scrutinised the primate archaeological record and concluded that the human brain has evolved just as would be expected for a primate of our size.

Here's another

The study examined ring-tailed lemurs, black-and-white ruffed lemurs and grey mouse lemurs, which differ in their social system, diet and brain size, not only among each other, but also compared to the previously tested Old World monkeys and great apes.

The results of the new study show that despite their smaller brains lemurs' average cognitive performance... was not fundamentally different from the performances of the other primate species.

This is even true for mouse lemurs, which have brains about 200 times smaller than those of chimpanzees and orangutans.

Isn't there some evolutionary pressure, and it could be that it applies to primates in general and not just humans, for big-headedness? Like if big-headedness didn't help, then you could imagine two populations, A and B, where A has big heads and B doesn't. B loses fewer mothers during childbirth. Those mothers can then give birth more times, making B grow faster than A, so after enough time, we're all medium-head B-people. But somehow we ended up with me not being able to hold my head up in baby pictures. What gives?

Brain size does matter, but we also massively increased its efficiency during evolution and developed social 'tools' to utilize it better.
