Re: Humphrys can make inadvertent fun out of anything

Hell, chickens have several million years worth of evolution....

Evolution doesn't necessarily mean becoming more intelligent. Remember that evolution doesn't really have a goal, so any change which promotes survival and reproduction will stick. The movie Idiocracy pretty well laid out an example of how evolution could diminish human intelligence. It was taken to the extreme, but the scenario is realistic.

In animals I could see several scenarios where the most intelligent members of the species don't last long. Perhaps the most realistic is a situation where a given species survival is so mind-numbingly easy that they don't need intelligence, in which case natural selection would get rid of it. Chickens are a pretty good example. A smart chicken might find a way to escape the farm, and that chicken, as a member of the bottom rung of the food chain severely lacking in any means of hiding and only having a relatively weak means of defending itself, would be doomed.
