Startup Colossal Biosciences has edited the DNA of a gray wolf to produce what it says is a de-extincted animal. Does that ...

Some question whether the pups are really dire wolves, or just genetically tweaked gray wolves. But the technology could be used to help at-risk animals.

Colossal Bioscience says it has “de-extincted” the dire wolf, but other scientists disagree and say more important ...

The dire wolf once roamed an American range that extended as far south as Venezuela and as far north as Canada, but not a single one has been seen in over 10,000 years, when the species went extinct.

“Preserving, expanding, and testing genetic diversity should be done well before important endangered animal species like the red wolf are lost ... altered coat color, texture, and thickness ...

The birth of red wolves provides further evidence ... of Colossal’s approach to engineering the light coat color into their dire wolves, I was simultaneously impressed and relieved," said ...

The company also reported the birth of cloned red wolves ... extinct traits unique to dire wolves, including skeletal structure, musculature, coat color, and hair length. Of these edits, 15 ...

Plenty of wolves that did not fit the right size or color for the red wolf might have been carrying what researchers refer to as “ghost alleles”—or red wolf gene variations that did not show ...

Colossal also produced two litters of Red Wolf puppies; the Red Wolf is an endangered ... altering their size and musculature, as well as the color of their coats, Shapiro said.
