Harvard Scientists Working on Bringing Back the Wooly Mammoth.

The woolly mammoth vanished from the Earth 4,000 years ago, but now scientists say they are on the brink of resurrecting the ancient beast in a revised form, through an ambitious feat of genetic engineering.

...“Our aim is to produce a hybrid elephant-mammoth embryo,” said Prof George Church. “Actually, it would be more like an elephant with a number of mammoth traits. We’re not there yet, but it could happen in a couple of years.”

The creature, sometimes referred to as a “mammophant”, would be partly elephant, but with features such as small ears, subcutaneous fat, long shaggy hair and cold-adapted blood. The mammoth genes for these traits are spliced into the elephant DNA using the powerful gene-editing tool, Crispr.

Church, a guest speaker at the meeting, said the mammoth project had two goals: securing an alternative future for the endangered Asian elephant and helping to combat global warming. Woolly mammoths could help prevent tundra permafrost from melting and releasing huge amounts of greenhouse gas into the atmosphere.

“They keep the tundra from thawing by punching through snow and allowing cold air to come in,” said Church. “In the summer they knock down trees and help the grass grow.”
