Discover the Truth: Colossal’s Gray Wolves vs. De-Extinct Dire Wolves Explained by Chief Scientist

On April 7, Colossal Biosciences created a buzz by announcing the return of dire wolves. They claimed to have resurrected these ancient creatures, which vanished over 10,000 years ago. However, the truth is a bit different. The three wolves, named Khaleesi, Romulus, and Remus, are not direct descendants but genetically modified gray wolves.

Colossal’s Chief Science Officer, Beth Shapiro, clarified that these "dire wolves" are essentially gray wolves with 20 modified genes. She emphasized that the company never intended to mislead anyone about their identity. "It’s not possible to recreate an exact replica of a species that existed long ago. Our wolves are gray wolves; we just made some changes," she explained in an interview.

This distinction sparked debates, as many scientists voiced concerns about the terminology. While some argue that naming them dire wolves is misleading, Colossal insists that if an animal looks like a dire wolf, it can be called one. Shapiro mentioned, "We chose the name because they reflect traits we found in the dire wolf genome."

The controversy partly lies in how we define species. Most scientists favor the biological species concept, which emphasizes the ability to interbreed, while Colossal uses the morphological species concept, which focuses on appearance. This difference in definitions can cause confusion.

For context, the concept of de-extinction has gained traction in recent years. In 2022, researchers published a study showing that the woolly mammoth could be revived through similar genetic editing techniques. As advances in biotechnology continue, discussions about what constitutes a species will likely become more complex.

Additionally, a survey from the Pew Research Center found that more than 50% of Americans are supportive of using genetic engineering to bring back extinct species. This reflects a growing curiosity and acceptance of scientific innovations in biodiversity.

Colossal’s efforts highlight the intersection of ethics and science. While these genetically modified wolves are exciting, they also raise questions about conservation, natural ecosystems, and species identity.

As the debate unfolds, the animals, raised in a controlled environment, continue to thrive. Some view them as a step towards enlightening the world on genetic editing and conservation efforts. The success of these wolves could pave the way for future projects focused on reviving other long-gone species, like the dodo or the thylacine.

In conclusion, while Colossal’s project has sparked intrigue, it’s essential to understand the implications behind naming and defining species in an evolving scientific landscape.
