Beautiful people have more daughters!

To whom it concerns,

This post is a plausible alternative answer(click on title)…. as to why some people produce children of one sex only. It is also a brief insight into how our ancestral mind could be influencing our modern mind.
I hope this was helpful.



Beautiful people have more daughters!

General knowledge on what determines your baby’s gender goes like this: chromosome Y for boys or chromosome X for girls. Doctors point out that

Other variables are the timing of conception, sexual position used the PH and acidity in the womb. If you go by old wifes tales it is important to keep in mind the moon phases.

Interestingly the Y (boy) sperm is very fast but also very weak and lives no longer than a day, whereas girls X’s are very hardy and can live days without weakening.

Evolutionary psychologist Satoshi Kanzawa has a different answer and I quote from an interview addressing : Our Ancestral Mind in the modern World:

SK: The basic idea is this: Whenever parents have genetic traits they can pass on to their children that are more valuable for boys than for girls, then they have more sons than daughters. Conversely, whenever parents have genetic traits they can pass on to their children that are more valuable for girls than for boys, then they have more daughters than sons. Physical attractiveness — being beautiful — is good for both boys and girls, but it’s much more advantageous for girls. Physical attractiveness of a woman is one of the most important considerations for men when they select both long-term and short-term mates, but a man’s physical attractiveness is important for women only when she’s looking for short-term mates. Women like to have affairs with good-looking men, but they don’t necessarily want to marry them, unless of course they are also rich and powerful.

So beautiful daughters will be more likely to take full advantage of their physical attractiveness than beautiful sons. Beautiful daughters are more likely to pass on their genes successfully to the next generation than beautiful sons, because they are more likely to find themselves in stable marriages to desirable spouses. In a representative sample of 3,000 young Americans, those who are “very attractive” had 36% greater odds of having a daughter compared to everyone else. Similarly, studies have found that big and tall parents are more likely to have sons, and short and thin parents are more likely to have daughters, because body size is more of an advantage to men than to women. Women are attracted to big and tall men much more than men are attracted to big and tall women.

If you would like to know more read the book by Alan S. Miller and Satoshi Kanazawa with the very long title:
