Scientists have pieced together part of the genetic recipe of the extinct woolly mammoth. The 5,000 DNA letters spell out the genetic code of its mitochondria, the structures in the cell that generate energy. The research, published in the online edition of Nature, gives an insight into the elephant family tree. It shows that the mammoth was most closely related to the Asian rather than the African elephant. The three groups split from a common ancestor about six million years ago, with Asian elephants and mammoths diverging about half a million years later. "We have finally resolved the phylogeny of...
