DNA proves mammoths mated beyond species boundaries
New research examining the DNA of North American mammoths challenges the way we categorize a species. Several species of mammoth are thought to have roamed across the North American continent. The new study results show that while mammoths clearly evolved differences in their physical appearance to deal with different environments, it did not prohibit them from cross-breeding and producing healthy offspring.

Is America planning with the Russians to ressurect the mammoth in a Jurassick park kind of scenario? The focus on the mammoth's DNA and genetics seems to suggest that its more than for just educational purposes.
