Biology and Gender
Humans exhibit sexual dimorphism in many characteristics, many of which have no direct link to reproductive ability, although most of these characteristics do have a role in sexual attraction. Most expressions of sexual dimorphism in humans are found in height, weight, and body structure, though there are always examples that do not follow the overall pattern. For example, men tend to be taller than women, but there are many people of both sexes who are in the mid-height range for the species.
Some examples of male secondary sexual characteristics in humans, those acquired as boys become men or even later in life, are:
- more pubic hair
- more facial hair
- larger hands and feet than women
- broader shoulders and chest
- larger skull and bone structure
- larger brain mass and volume
- greater muscle mass
- a more prominent Adam's apple and deeper voice
- a longer shinbone

Famous quotes containing the words biology and, biology and/or gender:
“The “control of nature” is a phrase conceived in arrogance, born of the Neanderthal age of biology and the convenience of man.”
—Rachel Carson (1907–1964)
“Nothing can be more incorrect than the assumption one sometimes meets with, that physics has one method, chemistry another, and biology a third.”
—Thomas Henry Huxley (1825–95)
“Most women of [the WW II] generation have but one image of good motherhood—the one their mothers embodied. . . . Anything done “for the sake of the children” justified, even ennobled the mother’s role. Motherhood was tantamount to martyrdom during that unique era when children were gods. Those who appeared to put their own needs first were castigated and shunned—the ultimate damnation for a gender trained to be wholly dependent on the acceptance and praise of others.”
—Melinda M. Marshall (20th century)
