OK but are you already epileptic? A video won't cause you to become epileptic, you know.

I wonder why flashing lights trigger seizures in some people. Perhaps way back in our evolutionary past there was some sort of predator that used bioluminescence to disorient prey animals, including our distant ancestors.

That doesn't really make sense: why would we evolve to become defenseless when flashed at? There's no benefit to it and quite a bit of risk. No, it's just a flaw when too much neurotransmitter molecules are released and things go FUBAR.

Not what I meant. I mean the whole "get messed up by flashing lights" might just be an evolutionary throwback to when we were as a species affected by that sort of thing. After all, many animal species today react weirdly to lights or use lights to get food, and there's a breed of goat that becomes partially paralyzed when scared. Throw the two together, and...

But apparently my musings were wrong anyway. So oh well.

But it was never a useful thing, it's just a problem that can't really be fixed. That's like saying that bleeding to death is an evolutionary throwback to when humans used to get bitten a lot.

Well, I believe it causes too much... is it GABA? to be released, which is a neurotransmitter.

Too much neurotransmitter, suddenly you're having action potentials all over the place, which leads to problems. Namely, seizures.

IIRC GABA was one of those that lowered postsynaptic potentials. Also, there might be some deal with calcium ion signalling between glial cells.

Ah, right. I must be mixing up the stuff used to treat it with the neurotransmitter.

Also, I thought calcium ions were only used at neuromuscular junctions? (which is why hydroflouric acid is so dangerous.)

It's not very well-known or described, but then again neither is epilepsy, but it seems glial cells in brain use calcium ion 'waves' to communicate throughout the brain and not just support the neurons but coordinate them. I'd link you the actual paper, but I first heard of it on a lecture and didn't write down the title, and it's been three months ago, so I kinda forgot :3

Regardless of what other people are saying about it being mere coincidence, I'm 100% certain that Angler Fishes used to be land dwelling creatures, a hideous race of fish people that used their bioluminescence to bring humanity to it's knees. It was the Neanderthals that sacrificed themselves in the long forgotten Fish V Cave Man war that drove them down into the depths of the oceans.

Naah, there's enough resources there - their problem is that the tech tree starts with the invention of fire.

BASIC resources.

The Antarctic lacks large amounts of food, as does the deep sea. They cannot start fires at the bottom of the ocean because water, and the Antarctic because lack of wood.

can't they import programmers and export petroleum and other stuff

They lack computers. Programmers would be useless.

then why would they need BASIC resources
