Researchers in Dallas, Texas, engineered grey-wolf blood cells and altered their DNA, leading to the cloning of three unique animals resembling dire wolves. Colossal Biosciences announced these animals in April 2024 as the first de-extinct creatures, with genetic edits reportedly matching sequences from dire wolves that lived 11,500 years ago. This announcement sparked contention among scientists, with critics arguing it misleadingly conflates cloning with true de-extinction. The company has responded defensively to such criticisms, highlighting the controversial nature of their claims and the broader implications for public understanding of de-extinction technologies.
Colossal Biosciences declared the birth of three animals from gene-edited cells as the first de-extinct animals, with genetic edits linking them to ancient dire wolves.
Researchers inserted nuclei from gene-edited grey-wolf blood cells into domestic dog egg cells, eventually cloning three animals resembling dire wolves—a significant breakthrough in de-extinction.
