Document Summary
The mating machine continued: quote by miller (2000) Parenthood and family: humans, essentially the only species that has sex recreationally and for please. Some indication that bonobos do so to some extent. Offspring gender why does it matter: males have a greater opportunity to create offspring and grand offspring, males, on average have greater chance to propel genes/ alleles into the future, sons are favoured over daughters . By 2020, china will have ~ 30millino males (1 in 10 in the age group. 20-45) who will not be able to find wives. This is ~ equivalent to the canadian population: this may possible be influenced by the 1-child policy. Also, the number of females are far less than the number of males. Hypothesis: evolution of preference of male offspring: desire to leave more inheritance to sons and daughters produced, drive to continue reproduction when daughters are born, maximizes family size of sons and daughters. Two outcomes: first: sons with wealth.
