Science has advanced significantly. Researchers have successfully produced a genetically modified “woolly mouse” that shares key traits with the extinct woolly mammoth. This remarkable accomplishment brings scientists one step closer to their ultimate goal of resurrecting the mammoth.
The Original Woolly Mouse
The woolly mouse was created, according to Colossal Biosciences, a de-extinction corporation. The first woolly-coated pups were born in October after scientists used sophisticated genetic engineering to implant altered embryos into lab mice.
“For us, it’s an incredibly big deal,” said Beth Shapiro, Colossal Biosciences’ chief science officer.
The mice’s fat metabolism is suited for cold survival, and they have thick, golden fuzzy coats. By contrasting the genes of mammoths with those of contemporary elephants and mice, these characteristics were discovered.
A Step Closer to Mammoth Revival
The success of the woolly mouse validates the genetic modifications scientists plan to apply to Asian elephant embryos. By editing key genes, they hope to create a mammoth-like elephant capable of thriving in Arctic environments.
“This is the way that we’re going to create mammoths for the future,” Shapiro explained.
Colossal Biosciences aims to produce modified elephant embryos by next year and birth the first mammoth-like calves by 2028.
Debate Regarding De-Extinction
Some scientists are doubtful about the accomplishment, while others applaud it.
“An elephant is not a mouse. According to Vincent Lynch, a biology professor at the University of Buffalo, “who knows if they could do the same thing with that species.”
Additionally, detractors contend that conservation initiatives need to prioritize preserving threatened species over bringing extinct ones back to life. Gabriela Mastromonaco, senior director at the Toronto Zoo, warned that de-extinction is a distraction from pressing conservation needs.
Potential Environmental Impacts
Despite the criticism, Colossal Biosciences says that reintroducing mammoth-like creatures might help restore ecosystems that have been degraded. Additionally, the business thinks that its genetic techniques might help prevent the extinction of contemporary species.
“We need new technologies to engineer life in a way that’s more adaptable to coexist with humans,” said Ben Lamm, Colossal’s co-founder and CEO.
As research advances, the world watches to see whether the woolly mammoth will walk the Earth once again.
