...long did it take humans to transition from a hunter-gatherer lifestyle to agriculture?” Smith asked in a slide...
...telephone press conference from Namibia, Hayes said the participants' advanced age (all were over 80) makes scientists confident that they are unlikely to carry rare genetic variations that lead to fatal disease, so they can focus on more subtle and common variations. Indeed, one of the participants, a Bushman hunter-gatherer known as !Gubi (the "!" expresses the palatal tick in his native language) was so robust that Hayes could not keep up with him in a rope-skipping competition. (See the top 10 medical breakthroughs...
...four hunter-gatherers had adaptive genetic variations, called single nucleotide polymorphisms, or SNPs, that may give them a survival advantage in the desert, researchers said: three men had two copies of variants associated with physical prowess and faster sprint performance, and one had a variant for a cellular mechanism that enables a person to retain salt and water - a benefit in a hot, dry climate. Yet another newly discovered genetic trait involved the ability to taste bitter chemicals, which could help hunter-gatherers avoid toxic plants...
...part, Tutu was delighted at some of the unexpected discoveries from his genes. He is Bantu, a traditionally agricultural people, and was included in the study to represent their ancestry. But his genome revealed that he is also maternally related to the San, a hunter-gatherer population that has traditionally lived around the Kalahari Desert. "The fact that the test found that I am related to these wise people who paint rocks makes me feel very privileged and blessed," he told...
...ecological disaster. But linguists stress that something vital gets lost with the death of each oral language. Anvita Abbi, a professor of linguistics at Jawaharlal Nehru University in New Delhi who spent the better part of the past decade studying the languages of the Andamans, says the speech of hunter-gatherer societies like the Bo carry an intimate, encoded understanding of the natural world and its biodiversity. Though the Bo seldom strayed from the few islands they inhabited, they have at least 67 words for varieties of birds and some 150 for fish. "There's a vast knowledge base slipping...
