i was thinking about the fact that animals that are considered living fossils, whose body shapes haven't really changed for the past few millions years, such as sharks, and other examples of adaptation pushed to the extremes, for some of these cases, i think they don't evolve simply because they are too well adapted - any other kind of significant mutation would reduce their adaptive fitness.
i think one factor in why people got huge brains is because we were ill-adapted to survival. of course, in some areas, we had advantage, like the ability to reduce our temperatures, but other than that, maybe we got a huge brain in order to maximise the environment, and since we didn't have inbuilt adaptations that allowed us to do that, we had to 'think' to create those tools.
but this is a lame idea.
