That's an interesting question. I think it depends on how far you go back with Grok ancestry. Perhaps as juveniles, maybe as adults. There are some evolutionary reasons why 'men' are afraid of approaching women. There was a real risk involved which could have meant a grok rock to your head for approaching the wrong female. It's why I thought the 'dancing' idea for 'attracting' females was so interesting. Non-violent ways of telegraphing alpha-maleness and attracting females. Doing things that reduced the risk of injury, yet showed strengh, charisma, and ability to females I think would probably be more appealing - such as with dancing. I'm not sure that grok was very warlike prior to 15,000 years ago, it would have went against the ability to survive as a group, playfighting could have resulted in injuries that kept you from hunting, moving, or protecting the group - but maybe that's how they weened the weak out? Maybe looking at chimp and gorilla groups would help answer this?
If someone has some links on hard research about this would be awesome!
