Neotonic features are an observable feature in ALL human species, the progression of them is the easiest way to identify species, or at least level of evolution at aglance. Modern humans do have brow ridges, albeit redused in size, most pronounced in Caucasoids and of them, Melanoids/Australoids most of all. Usually. Also more with taller, most robust Caucasions elsewhere.
You can't tell psychological states from fossils, that's silly.
You can, however, tell from a narrowing of difference between male and female size that monogamy became part of the question, and early on in human evolution. So your 'promicsuous" assertion, like the rest of your post, is nonsense.
Lions are closer to tigers, not leopards.
