    Interesting. It seems to have a blind spot of "what evolution want", though it does exposes that point "because evolution’s goal isn’t to make you happy, it’s to maximize reproductive fitness."

    And so, from the very same premise, evolution don’t necessarily need individuals that are long standing, even less in environment which are themselves very unstable. As long as species continues to exists, evolution made its job. In more stable environments, long life span is causing less pressure on chance for the species to remain viable. A large motile animal in ocean don’t have to face that much significant changes in environment compared to their out-of-water counterparts. Of course the environment alone don’t explain everything in term of most efficient strategy, size matter, mobility mode matters, how much of such an environment exist and how large the population can grows before facing a demographic cap, just to cite the first that comes to mind.

    I’m not a biologist, at all, and even a random layman as myself can comes with these obvious ideas.

    That said, I also have all kind of blind spots, no doubt about it, and I didn’t even write a very nice to read issue on the topic unlike the author of TFA.
