Search Results: why do girls rate other girls

Some people claim it's mostly due to society (many of them call it "gynocentrism", a focus on women's well-being and not men's), but if that was the case, then males wouldn't have higher mortality rates in almost all species, & throughout life, even in the womb:

"External maternal stress around the time of conception is associated with a reduction in the male to female sex ratio, suggesting that the male embryo is more vulnerable than the female... The male is at greater risk of death or damage from almost all the obstetric catastrophes that can happen before birth. Perinatal brain damage, cerebral palsy, congenital deformities of the genitalia and limbs, premature birth, and stillbirth are commoner in boys, and by the time a boy is born he is on average developmentally some weeks behind his sister: “A newborn girl is the physiological equivalent of a 4 to 6 week old boy.”"

"Females of most species live longer than the males... Cells in a female body repair damage better than in the body of a male... Surgical removal of the ovaries eliminates this difference... In one study... castrated men were found to live on average 14 years longer than their uncastrated fellows."

"When a mutation of one of the genes of the X chromosome occurs, females have a second X to compensate, whereas all genes of the unique X chromosome of males express themselves, even if they are deleterious... Furthermore, female hormones and the role of women in reproduction have been linked to greater longevity. Estrogen, for example, facilitates the elimination of bad cholesterol and thus may offer some protection against heart disease [the biggest killer of both men and women]; testosterone, on the other hand, has been linked to violence and risk taking." https://www.scientificamerican.com/article/why-is-life-expectancy-lo/
