Mammoth project

The recipe for making any creature is written in its DNA. So last November, when geneticists published the near-complete DNA sequence of the long-extinct woolly mammoth, there was [blank] speculation about whether we could bring this behemoth back to life. Creating a living, breathing creature from a genome sequence that exists only in a computer's memory is not possible right now. But someone someday is sure to try it, [blank] Stephan Schuster, a [blank] biologist at Pennsylvania State University, University Park, and a [blank] force behind the mammoth genome project.
