Before I start on some of the alien stuff I mentioned, please note that I'm not saying any one thing or theory I mention has presented itself to me to be a guaranteed sole cause, they are simply "possibilitys" that have some degree of backing.
Since I don't have my reference bookmarks handy you will have to look this up on your own.
In an ancient myth of a African tribe that are said to originated in Egypt before it was egypt, it is said that most current life on earth is a result of what amounts to a process to repair damage caused by an experiment conducted by an alien race that unintentionally went fubar.
The tribe is called the Dogon and the Alien race is called the Nomo/Nummo, a race that were female by default, but would become male temporarily when needed for reproductive purposes.
(much like several spices of frog & fish)
long story short humans were seemingly engineered to end up the same gender wise as the nummo eventuality.
I'll look up a couple audio blogs I know of that describe this far better than I can from a smartphone and post them later.
