MADRID, April 1, 2008 (AFP) - Climate change pushed the woolly mammoth to extinction even if it was hunting by our ancestors that finally finished off the species about 3,500 years ago, a Spanish study said Tuesday.

Using climate models and fossil remains, researchers concluded that the habitat available to the mammoth had shrunk by 90 percent as glaciers receded through the ages.

WASHINGTON, Sept 27, 2007 (AFP) - Scientists have sequenced the DNA in the hair of woolly mammoths dating back 50,000 years, paving the way to further research on many extinct species, according to a study published Thursday.

'Hair shafts are a promising source of DNA,' said the authors of the study from the University of Pennsylvania and the University of Copenhagen, published in the September 28 edition of Science.
