Thanks Roz. I think the evolutionary psychology perspective is quite interesting. There is a real fundamental logic to it . . . and yet it somehow leaves you wanting (at least for me). I am left with a feeling of, “Oh, that can’t be all there is to it, can it? There must be more to all the complexities of human behavior than just that.” It’s a bit like the pure behaviorist perspective in that respect. But they both do seem to be a piece of the puzzle and answer some of the myriad of questions.
