Ancestor

On a remote island in Lake Superior, scientists struggle to solve the problem of xenotransplantation: using animal tissue to replace failing human organs. Funded by the biotech firm Genada, Dr. Claus Rhumkorrf strives to recreate the ancestor of all mammals, and use it to genetically engineer a self-sustaining herd of organ-donor animals. The process will save millions of lives, and make billions for Genada. Rhumkorrf discovers this ancestor, but it's not the docile, harmless creature he envisions. His genius gives birth to a fast-growing evil that nature eradicated 250 million years ago. An evil now on the loose, and very...very...hungry.
