I enjoyed the reaserch data on sexual identity being as many other reaserchers are finding out in other fields conserning human behaviors etc a hardware thing as much as a software thing.

Structure = function is after all the mantra of more than just anatomy and phisiology.

Are we actually evolving into some sort of mass global culture in which monogamy will one day become obsolete?

Perhaps....but not anytime soon is my guess, not without making radical changes to our genetic makeup to speed it along, outside simuli (such as enviromental changes ie urbanization and modernization) can only influence one to a certian extent.

Certian anthropological behaviors conserning the survival and propogation of the species have worked better than others and are very much a part of one's hardware or nature as opposed to others.

It shouldnt be a surprise that humanitys breeding habits are not as far off from their closest kissing cousins in the animal world as humanity would like to think.

If anything serial monogomy may be proven to be more of an illussion is all, like the difference between the romantic ideal of somthing and the reality of its function in actual practice.
