How Culture Influences Violence among the Amazon’s ‘Fierce People’
When Yanomamö men in the Amazon raided villages and killed decades ago, they formed alliances with men in other villages rather than just with close kin like chimpanzees do. And the spoils of war came from marrying their allies’ sisters and daughters, rather than taking their victims’ land and women. (more…)
EAST LANSING, Mich. — Witch hunts are common and sometimes deadly in the tea plantations of Jalpaiguri, India. But a surprising source – small groups of women who meet through a government loan program – has achieved some success in preventing the longstanding practice, a Michigan State University sociologist found.
Soma Chaudhuri spent seven months studying witch hunts in her native India and discovered that the economic self-help groups have made it part of their agenda to defend their fellow plantation workers against the hunts. (more…)
One of the largest and longest studies in a traditional African society sheds light on religious practices and cuckoldry. Genetic data suggest religious patriarchy is directly analogous to the mate-guarding tactics used by animals to ensure paternity.
Religious practices that strongly control female sexuality are more successful at promoting certainty about paternity, according to a study published in the June 4, 2012 issue of the Proceedings of the National Academy of Sciences.
In an interdisciplinary collaboration, a group of researchers around biological anthropologist Beverly Strassmann from the University of Michigan and University of Arizona geneticist Michael Hammer analyzed genetic data on 1,706 father-son pairs in a traditional African population – the Dogon people of Mali, West Africa – in which Islam, two types of Christianity and an indigenous, monotheistic religion are practiced in the same families and villages.

Hosted by world-renowned astrophotographer Adam Block at the UA’s Mount Lemmon SkyCenter, a group of sky and astronomy enthusiasts watched Venus cross the sun from the highest vantage point in Southern Arizona.
On Nov. 24, 1639, in the tiny village of Much Hoole not far from Liverpool, England, a poor farmer’s son and self-taught astronomer affixed a sheet of paper in front of a makeshift telescope pointed at the sun and waited.
Thirty-five minutes before sunset, a dark, round spot appeared right next to the bright disc that was the sun’s face projected on the paper, and made Jeremiah Horrocks, only 20 years old at the time, the first known human to predict, observe and record a transit – the passage of a planet across the sun as seen from Earth.
Almost 373 years later, a group of sky enthusiasts is gathered beneath the dome of one of the University of Arizona’s observatories on Mount Lemmon just north of Tucson, Ariz. (more…)
