Humans differ in paternal investment—the degree to which fathers help mothers care for their offspring. They differ in this way between individuals, between populations, and between stages of cultural evolution. During the earliest stage, when all humans were hunter-gatherers, men invested more in their offspring with increasing distance from the equator. Longer, colder winters made... Read More

Tanned arm (source). Underarm skin color used to be a reliable measure of constitutive pigmentation (skin color before tanning). Is it still? After puberty, girls become lighter-skinned than boys. This sexual differentiation has been shown to be hormonal in origin by a digit ratio study (Manning, Bundred, and Mather, 2004), by studies on normal, castrated,... Read More

Child making Nike shoes (source). Western business now has access to labor under conditions not seen since the days of Charles Dickens. My predictions from last year: It won’t be such a bad year. Stock markets will reach record highs and pundits will say we’ve entered a sustained boom. For many people, life will never... Read More
Hue and Luminosity of Human Skin: a Visual Cue?

•ï¿½200 Words •ï¿½6 Comments • Reply
The inferotemporal cortex is involved in both face perception and color perception. It may be in this region that the brain processes visual data on the hue and luminosity of human skin. If you are a member of the International Society for Human Ethology, you can read my latest article: Hue and luminosity of human... Read More

Averaged face of blue-eyed male subjects (left). Averaged face of brown-eyed male subjects (right). Czech population. (Kleisner et al., 2010) If sexual selection of women diversified the eye color of early Europeans, the new colors should tend to be sex-linked, since the selection targeted women more than men. There is now evidence that blue eyes... Read More

Time to die. This parasitic fungus begins as a spore on an ant’s body. It germinates, grows inside its host and eventually directs the ant’s brain to climb a plant and clamp its mandibles around a leaf or stem. The fungus then kills its host. It won’t be such a bad year. Stock markets will... Read More

Averaged female face (left) and averaged male face (right). The key facial regions for gender recognition, in terms of either response time or accuracy, seem to be where facial skin borders the lips or the eyes. The human face is a special visual object. We do not learn to recognize it. Instead, it is processed... Read More

The human mind seems to use facial color to determine whether a person is male or female. A man has a relatively dark facial color that contrasts poorly with his lip and eye color. Conversely, a woman has a relatively light facial color that contrasts sharply with her lip and eye color (Russell, 2003; Russell,... Read More

Are ruddy faces attractive? Apparently they are—if we believe the findings of a study from the University of St. Andrews, Scotland (Stephen et al., 2009). The subjects were presented with photos of male or female faces, one at a time, and asked to give the faces an optimal healthy appearance. This was done by manipulating... Read More
