Using meta-analysis of neuroimaging, researchers have concluded that these areas are linked to sexual preferences in humans, which would explain why they may differ based on sexual orientation. [ 7 ] Another area of the brain which demonstrates sexual orientation differentiation is the thalamus, which is a structure involved in sexual arousal ...
For example, male traits such as the presence of beards, overall lower voice pitch, and average greater height are thought to be sexually selected traits as they confer benefits to either the women selecting for them, or to their offspring. Experimentally, women have reported a preference for men with beards and lower voices. [2] [3] [4]
Anthropologist Peter Frost has proposed that sexual selection for women with unusual hair or eye color was responsible for the evolution of pigmentary traits in European populations, [128] however this theory has since been refuted by data-based evidence from genetics and spectrophotometry, [129] [130] and multiple studies have shown that women ...
The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]
In 2010, Archives of Sexual Behavior published a study comparing the pedigree sizes of 694 homosexual men and 894 heterosexual men sampled at pride parades that found that homosexual men had more relatives, especially paternal relatives, but no evidence that male sexual orientation is transmitted predominantly through the maternal line—which ...

Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect, direct being the direct result of differences prescribed by the Y-chromosome (due to the SRY gene ), and indirect being characteristics influenced ...
