The always-readable Nichols Wade had a good article in the NYT earlier this week on how we've taken one small step toward possible mammoth cloning - and how the debate about whether cloning will ever be practical continues unabated. "A large fraction" of the extinct pachyderm's DNA has been recovered from fragmented specimens using new machines and techniques. One of the men announcing this advance, Penn State University's Stephan C. Schuster, estimates he could recover the entire genome for another $2M and clone a mammoth for $10M.
