First off, I love that picture you used at the top of your article.
Second, your combination of rough language while discussing these rather high level concepts is really unique to me as in:

"Small groups of males and females gang-banged together and created large families."

Haha I'd have definitely gone with "group sex" over "gang banged" but you certainly make your point known with little filter.

Love the article and totally agree with the intent of where you're going with it. We as people should be able to enjoy sexuality in the way we wish as long as we're open, with those who can offer consent, and hopefully in responsible cultures that respect people and their autonomy as human beings and sexual creatures. Living in Cambodia has shown me how easy it is for economics and societal pressure can completely dominate the ability to make one's own choices about love and desire. I'm still struggling with the idea of ethics in societies that teach young girls from birth that they are sex fodder for old men and have no value outside of their sexuality and childbearing abilities.

Also, if anyone reads comics, there's actually an awesome Flinstones comic out right now they completely make the point of homosexuals helping out with child rearing. It's like issue 8 or something. Hilarious and just fantastic modernization of the "modern stone age family."

My only real challenge to the piece is the idea of "alphas" as some sort of natural state for humanity (not that you were saying it was but I want to get the info out as much as possible). We're just too complex for that, mirroring our closest genetic cousins (chimps and bonobos) in some ways and completely rejecting others. Our social structure almost seems hardwired from "gay for the stay" in prison or the interesting scenario posed here where rampant sex by elites adversely affected the masculinity and sexuality of males in worse standing. Some would definitely make an argument like that for aspects of the American Black community's sexual fallout from slavery. They say in books like Sex at Dawn that widespread agriculture 10,000 or so years ago completely changed the importance of things like knowing one's parentage, female chastity, and even the concept of ownership - completely reversed after storing food was no longer taboo and being in once place suddenly mattered.

Anyway! It's an interesting book. Great post and thanks for writing it. I'm glad I followed you for sure.
