...young parliamentarian who sponsored the bill. He received a warm reception from the audience of a few hundred people, many of them students. "They say that if you are a homosexual, you are more likely to contract AIDS," Bahati said, to applause and laughter. "If you are a homo, you can reduce your life span by close to 20 years!" Bahati is a member of the Family, a fundamentalist Washington group that has been criticized for allegedly sending influential U.S. Senators and Representatives overseas to promote anti-gay and antiabortion policies, according to Jeff Sharlet, a journalist who wrote...
...Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action...
...Revolution, modern humans have grown taller and stronger, so it's easy to assume that evolution is making humans fitter. But according to anthropologist Peter McAllister, author of Manthropology: the Science of Inadequate Modern Man, the contemporary male has evolved, at least physically, into "the sorriest cohort of masculine Homo sapiens to ever walk the planet." Thanks to genetic differences, an average Neanderthal woman, McAllister notes, could have whupped Arnold Schwarzenegger at his muscular peak in an arm-wrestling match. And prehistoric Australian Aborigines, who typically built up great strength in their joints and muscles through childhood and adolescence, could...
...ability to climb. Her foot had an opposable big toe for grasping tree limbs but lacked the flexibility that apes use to grab and scale tree trunks and vines ("Gorilla and chimp feet are almost like hands," says Lovejoy), nor did it have the arch that allowed Australopithecus and Homo to walk without lurching side to side. Ardi had a dexterous hand, more maneuverable than a chimp's, that made her better at catching things on the ground and carrying things while walking on two legs. Her wrist, hand and shoulder bones show that she wasn't a knuckle walker...
...climate has swung drastically and often abruptly from one state to another - from tropical swamp to frozen ice age. Over the past 10,000 years, however, the climate has remained remarkably stable by historical standards: not too warm and not too cold, or Goldilocks weather. That stability has allowed Homo sapiens, numbering perhaps just a few million at the dawn of the Holocene, to thrive; farming has taken hold and civilizations have arisen. Without the Long Summer, that never would have been possible...
