Ok, lets break it down - humans are a large group of people with a lot of different life goals and motives and their selection of mates can't be generalized as such. Not all humans fit into little boxes such as "alpha male." Or even "male" and "female." What are "good genes" anyways that these "alpha males" supposedly possess? Why are they good or desirable? Do women care about genes when selecting a partner or are partners selected some other way such as the mere-exposure effect or for cultural reasons? Who are these "alpha males" who desire to never setting down ever and do nothing but have sex with multiple women for the rest of their lives? There certainly isn't a dichotomy of men - those with "good" genes that women swoon over but refuse to raise a child and those with "bad" genes that women don't want but will raise children. Then the rapist hiding in the shadows who are somehow not part of society and don't have consensual sex ever? That is obvious if you spend some time with, well, anyone. Making extremely broad and silly assumptions about groups of people is just not productive.
Every single person I know who is male and has lots of sexual partners are the ones who really do want to raise children and "settle down," probably moreso than their peers with less sexual partners. But they wanted to have years of sex with lots of women first then when they get older raise children. The women they have sex with don't want "genes."
What about people who want to adopt, gays who may or may not want children, asexuals who may or may not want children? Etc. Most people who don't desire children also desire a mate so what do they look for?
Anyways, it was completely off topic. It doesn't relate to lizards in any way whatsoever.
