No. The plain basic truth of life is the some humans are better than others. Smarter. Better looking. More attractive. Healthier. Stronger. Faster. With more endurance. With a better development of the PFC.
Yes, some humans are better than others. Besides, look at what enormity you wrote. You accept that humans are not equal, not born with same genes, nor having access to the same social nurture, but you don't accept that some are better. Embrace the truth my friend, some humans are orders of magnitude better than others :P And yeah, some men will get more women in a year than others in a lifetime.
If you read my post carefully, you will realize that I didnt said that genes are the only determinant of the behavior. This is something you imagined in your head. You have to start to differentiate between modulation and determination.
The contradictions are only in your head. I never suggest that is impossible to learn some things. I suggested that when you reach elite levels, genetics become important. You are naive if you beleive that a human can do anything he wants to do and raise to any level. Some simply don't have what it takes. Let's face it , we are not living in a world full of elite sprinters, elite scientists and extremely successful businessman which all have incomes of over 7 zeroes / year. The average humans are beings with no particular success in anything, but to bring some food at home. Blank averages. Nobody will remember them for anything but their immediate family.
Genetic propensities are important. Get a lower development of the PFC than your high school playmate, and chances are that you will end lower in the social hierarchy then him. As idiotic as it may seen, development of PFC in childhood are a very good predictor of where you will end on the social ladder.
No. Take any course in evolution at any university worth its salt and you will be told the same thing as I did told you. Survival of the fittest is a idiotic misnomer. Something for pop science on Discovery and the likes.
You would think that is wrong, but again, you fail to understand it. First , you can lave homosexuality apart. I was talking about heterosexual relationships. Second, all those things are pretty much statistical significant. This ofc does not exclude the existence of deviant behaviors, such as humans who dont want to be treated nice, or man who prefer to sleep with women overflowing masses of fat.
