    It the only reason why intelligent, civilization building species developed on land and not on the ocean floor the lack of energy to drive necessary ecological complexity and amount of biomass it subsists on? (Land gets up to 1kW/m2 from the sun, and most ocean is dark.)

        Or is the problem that structure requires symmetry breaks through separation, and the ocean is 3d while land is 2D?

        No, but I think that it is likely. There are also a number of designs that evolved on land and went back into the ocean (outcompeting ocean dwellers). The land may have been the ocean's MIT. :)

        Even without food limits, energetics are unfavorable to support big brains. Water is 800 times denser than air, and 1/30th of the oxygen, so mass flux to fuel the body is much higher. Endothermy very hard in water due to specific heat (my PNAS 2017 & bioRxiv 2019)

        Thank you, that makes a lot of sense. Cetaceans seem to be the only known ocean dwellers with large brains and long childhoods, and they are air breathing and homeothermic. Some sharks come close, though. I wonder where the limit for krakens lies.

        Great question and my initial answer was that you can't swing a hammer with enough force to knock in a nail, but then I thought - it's cause all the water keeps putting out the metallurgical furnace fires. But the real answer is fins don't grow opposable thumbs.

        Worse: you cannot write under water, so there are no nerds in aquatic societies, and all the dolphins and octopi ever talk about is sports and sex.

        I would add @malcolmmaciver’s point that the key cognitive difference between water & land is long-range visibility. Only through air are eyes able to see far ahead and thus plan far ahead with ever bigger brains.https://twitter.com/seanmcarroll/status/1110183986305757185?s=21 …

        In most circumstances, I can only see a few dozen meters at best, before there is an obstacle that hides whatever goes on at the ground level...

        Yeah, there is not much food to start with and it's difficult to store/hoard in water. On land you can just pile up grain as long as it is dry.
