Man's best friend lends insight into human evolution

...domestic dogs is nothing other than the process of domestication ?the breeding of dogs to tolerate, rather than fear, human company. According to Hare, domesticated dogs' ability to solve social problems may have emerged once the brain systems mediating fear were altered ?and the same thing may have occurred in...

Wheat gene may boost foods' nutrient content

...-B1, suggesting that this gene was lost during the domestication of wheat. Therefore, the reintroduction of the functional gene from the wild species into commercial wheat varieties has the potential to increase the nutritional value of a large proportion of our current cultivated wheat varieties," he said. "F...

New evidence of early horse domestication

...on," says Sandra Olsen, an archaeologist and horse domestication researcher at the Carnegie Museum of Natural Histo...esticate horses, says Olsen. "The very first horse domestication was probably a bit earlier in Ukraine or western Russia," she said. "Then some horse-herders migrate...

Better sludge through metagenomics

...xpect that clues hidden in the genome will lead to domestication of this mysterious organism, enabling further studies of its habits and lifestyle. "The genome sequence will also enable biologists and engineers to understand why and how these organisms accumulate phosphorus, and it will lead to major advances in...

Tamed 11,400 years ago, figs were likely first domesticated crop

...hat the dawn of agriculture may have come with the domestication of fig trees in the Near East some 11,400 years ago, roughly a thousand years before such staples as wheat, barley, and legumes were domesticated in the region. The discovery dates domesticated figs to a period some 5,000 years earlier than previousl...

Biologists find regions of rice domestication

... pretty readily, so I was fully prepared to see no domestication signal whatsoever," Schaal said. "I would have expected to see clustering of the cultivated rice, but I was delighted to see geographical clustering of the wild rice. I was thrilled that there was even any sort of genetic structure in the wild rice...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...ts themselves using techniques such as accelerated domestication to make them more efficient energy crops. But doubling the productivity of energy crops will mean identifying constraints and correcting them with genomic tools. To make biofuels a truly practical alternative to petroleum, the group says there will...

Lactose intolerance linked to ancestral environment

...ase of how cultural evolution -- in this case, the domestication of cattle -- has guided our biological evolution." Although all mammalian infants drink their mothers' milk, humans are the only mammals that drink milk as adults. But most people -- about 60 percent and primarily those of Asian and African descent ...
