The differences between male and female general evolutionary interests can be better understood through the analysis of the various factors that affect sexual conflict. In situations involving a male and female, only the relative positions of the optimal trait values are important as it is their comparative positions that provide insight into ...
[9] [8] Examples include greater male tendencies toward violence, [10] or greater female empathy. The terms "sex differences" and "gender differences" are sometimes used interchangeably; they can refer to differences in male and female behaviors as either biological ("sex differences") or environmental/cultural ("gender differences").
The human brain. Differences in male and female brain size are relative to body size. [85] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
There are different models that attempt to describe the relationship between gender and stratification. One model is the sex-differences model which discusses the differences in behavior and attitude when called on the labels of male and female. [18] Further, it is attempting to locate the true difference when all "socialization is removed". [19]
In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
Skeletons of female (left) and Male (right) black-casqued hornbills (Ceratogymna atrata). The difference between the sexes is apparent in the casque on the top of their bill. This pair is on display at the Museum of Osteology. Sexual dimorphism may also influence differences in parental investment during times of food scarcity.
When synthesized, these differences show that volume increases for males tend to be on the left side of systems, while females generally see greater volume in the right hemisphere. [5] On the other hand, a previous 2008 meta-analysis found that the difference between male and female brain lateralization was not significant. [25]
Conflict theories are perspectives in political philosophy and sociology which argue that individuals and groups (social classes) within society interact on the basis of conflict rather than agreement, while also emphasizing social psychology, historical materialism, power dynamics, and their roles in creating power structures, social movements, and social arrangements within a society.
