"Scientists Say They’re Closer To Reviving Mammoths. What Could Go Wrong?"

"The plan to bring back the woolly mammoth — or at least a version of it — is ambitious but raises hairy questions".

"A company aiming to bring extinct animals back from the dead said it has taken an elephant-sized step toward genetically resurrecting the woolly mammoth, a wild if contentious goal to repopulate the Arctic tundra with a missing titan.

Colossal Biosciences, a biotechnology company based in Dallas, announced Wednesday it has produced a line of Asian elephant stem cells that can be coaxed to transform into other types of cells needed to reconstruct the extinct giant — or at a least a mammoth-like elephant designed to thrive in the cold.

“It’s probably the most significant thing so far in the project,” said George Church, a Harvard geneticist and Colossal co-founder. “There are many steps in the future.”

For proponents, bringing back vanished animals is a chance to correct humanity’s role in the ongoing extinction crisis. Breakthroughs in their field, they say, may yield benefits for animals still with us, including endangered elephants."
