The male/female ratio is close to 50/50. Men on online dating sites just don't seem to realize online dating is simulating real world dating. In real world dating, the guys tend to go for the girls not vice versa. On online dating, it is still the same.
Alpha male and evolution as reasons would make a lot of sense to me prior to the modern era, where options for women were limited, survival of new families was more difficult, and women were generally not encouraged to be so forward.
I don't think it is required, but it is an interesting question why it turned out that way.
Could be that women are simply lazy and avoid the risk of rejection. They will be approached anyway, so they don't have to move themselves. Also, women usually do make the first step, just not the obvious one of walking up and talking.
I just had to think that it might be a bad strategy for women, because I am a bit like that with recruiters. I am usually too lazy to approach companies I desire to work for and end up working for the next best project a recruiter pushes to me once my bank account falls below a certain threshold. Naturally that way I end up with lots of sub par projects.
IRL, most men are too timid to approach women the same way it's done on dating sites. Can you imagine a bunch of average guys going around in the streets and talking to random women in broad daylight with no hesitation?
When you take away Approach Anxiety, of course you're going to have a massive storm of sausage looking for action. Because, while it sounds cliché, men really are pigs (or more accurately, chimps). :-)
