Mammoth Dawn - Gregory Benford - Bog

Extinction is not permanent. Not anymore.
Multi-millionaire researcher Alex Pierce has developed cutting-edge genetic techniques to extract viable DNA from preserved samples of breathtaking species that humans have erased from the Earth. From passenger pigeons and Tasmanian tigers, to Pleistocene dire wolves and sabretooths...even the humble dodo.
The cornerstone of Alex's dream is to resurrect the woolly mammoth. Majestic and massive, these creatures no longer roam the world, driven to extinction by ancient hunters. At his isolated Pleistocene Ranch in the wilds of Montana, Alex has actually bred the very first mammoth to walk the Earth in 10,000 years.
But there are those who believe what is extinct should remain extinct, and that any tampering goes against the laws of nature. And their fervor may be far stronger than Alex's dreams.
Mammoth Dawn is the original acclaimed novella written by New York Times bestseller and Hugo and Nebula Award nominee Kevin J. Anderson and multiple Hugo and Nebula winner Gregory Benford; this volume also includes their detailed chapter-by-chapter treatment of the full novel the two authors originally envisioned, as well as a non-fiction overview of current scientific attempts to clone mammoths-a reality that may be much closer than you think.
