Cavemen Come to Life, And Not Just on TV

Researchers from the Max Planck Institute say they can reconstruct the sequence of the Neandertal genome. To overcome the damage done to the DNA over the years, Svante Paabo and his colleagues will be using DNA from several individuals and they are taking steps to prevent contamination by human DNA. Paabo and his colleagues also plan to reconstruct mammoth and cave bear genomes.

Maybe this study will answer that age-old question: Is it really so easy that a caveman can do it?
