We bump against the reality you speak of all the time – our brains haven’t changed much in 100,000 years. Evo adaptation takes a very long time. But why? Shouldn’t it be most effective to keep up in some way with societal trends? I understand that you’d want to let enough time pass to identify which adaptations truly make sense, but it does seem as if the process is inefficient. Some think we’ve stopped evolving. Sorry for the stupid question, I am just a bit confused about the glaring gap between our evo programming and contemporary society. We’re still rewarding alpha male behaviors that are detrimental today, even if they helped bring home the bacon in 10,000 BC.

“I suspect this is directly related to the stigma of STDs.” . I doubt it – we know that the visceral power of the tingle is strong, so to not sleep with a sexually capable man, the tingle must be being countermanded by another visceral hindbrain force. I’m guessing the hindbrain has a stop-order (so to speak) in for ridiculously promiscuous men, possibly because it signals lack of selectivity and thus poor investment on the man’s part, or because by simple math he must be doing some low-SMV women in that batch and that’s a DLV/anti-preselection.

“We bump against the reality you speak of all the time – our brains haven’t changed much in 100,000 years. Evo adaptation takes a very long time. But why? ” . I’m not sure I entirely buy your premise. I believe I read that we have undergone tremendous genetic evolution since we moved into cities about 50,000 years ago. Human and natural events further influence subpopulations. For example, destructive wars of the last 300 years have put huge selections pressures on the Russian population.

@Susan and Badger
Our first permanent settlement with a major agricultural basis only came about around 10,000 years ago – or about 500 generations ago (assuming a 10,000 yr average age of childbirth of about 20 yrs old), which in evolutionary terms is pretty recent. In dog terms (say avg of a dog’s first litter being about.. 2 yrs old, perhaps?). That means 500 generations of dogs is only about 1,000 years.
I don’t think anybody on this board would $100 that dogs of 1,000 yrs ago are psychologically/behaviorally different from today’s dogs – and this despite conscious and deliberate intervention by humans to select for personality/temperament characteristic! Who or what breeds even a substantial fraction of the human population for certain traits?
