This question could be asked about sex: the verb or sex: the noun. In noun form, sex (or sex assigned at birth) is a term used to describe physical or genetic markers ? more specifically, hormones, genes, and reproductive organs. Biologically speaking, it's a myth that there are only two sexes, male and female. All physical sex characteristics ? from genitals, to hormones, to chromosomes ? fall...

In an attempt to explain the superior spatial skill of males, several studies have investigated the hypothesis that spatial ability is enhanced by an Xlinked recessive gene. Some of the evidence based on intrafamilial correlations supports the X-linkage hypothesis of superior male spatial ability (Stafford, 1961 ; Hartlage, 1970; Bock and Kolakowski, 1973; Yen, 1975) while more recent work, inc...

Genetic correlations between the sexes can constrain the evolution of sexual dimorphism and be difficult to alter, because traits common to both sexes share the same genetic underpinnings. We tested whether artificial correlational selection favoring specific combinations of male and female traits within families could change the strength of a very high between-sex genetic correlation for flowe...

The concept of human nature played an important role in the Aristotelian attempt to characterize the specific difference of humans from other animals and serves as a normative guide. But with the positivistic turn in the modern conception of nature and the denaturalization of reason (typically since Kant), the essential characteristic of human beings can no more be thought of as "natural". The ...
