You would think that the genetics for shyness would have disappeared. By now everyone should be super outgoing and over-brimming with self confidence.
I don't necessarily think this is what women want. Just as their are alpha and beta men, there are also women who desire the alphas AND women who desire the betas. Some women are drawn to overtly powerful men while others get attracted to less superficial features, such as character, intelligence, compassion, etc.
I do find it interesting (and scary in many ways) that many of the movies being made these days for the younger generations portray men as helpless boobs who need strong, smart, sexy, dynamic, yet, submissive women to take care of them. To me, it is a redefinition of what it means to be a man. This goes back a ways where men were often portrayed this way, but, they were less typified as the moronic stereotype they are these days.
In the end, scientific theory is too clean-cut to be accurate. Reality is shyness is a behavioral characteristic, not a genetic trait. And, when you say, "by now", it implies we are far enough along in our march towards eugenic perfection to have genetically eradicated this type of "flaw"? Again, I am not sure the OP even knows that this "theory" is a bad start from the word go.
