Earlier man had a larger brain than us, but that's because our brain became more efficient, so the brain got smaller. If 2 people had the same size brain, but one was smooth, and the other had many folds in it, it would make sense that the brain with more folds would be better, because it would have a greater surface area. So size isn't everything.

I think that the fact that bees need to be fundamentally light to be flightworthy also creates an unwanted bias. This might give the assumption that animals capable of flight are very smart when in reality us earthbound critters just have heavy bones lol

I think it's the first time I heard that we don't actually know what a brain is.
If more of what we don't know was mentioned at education we could have more motivated students, sometimes is like we know everything to be known, and that may be discouraging.

Ok, this episode made me realise two things:
1. I gotta look into these ctenophore thingies
2. Starfish are what happens when you slice a sea cucumber sagittally in five - (for real, I did not know they were bilaterians)

I've held a lot of honey bees that need assistance (hence my pfp, and they feel intelligent. Bees never sting me even though I handle them because it's almost as if they know that I don't pose a threat.

I sound like a broken record, but this video was wildly entertaining, excitedly informative and wonderfully presented in a way that is easy to understand. Great, great job!

Bruh, we deadass spent all this time evolving, building big brains to use on tools just so fools could STILL comment -first- 5 times on every new video on the internet.

I loved the way intelligence was explained. This is a really important point to consider: animals are intelligent beings in its own way.
