Guest: Kate Allen, Toronto Star climate change reporter

When the movie Jurassic Park was made in 1993, the technology at the heart of its plot — bringing ancient giant animals back from extinction — was in the same category as time travel and warp drives: science fiction. This week it seems it may be closer to being just plain science.

After a company named Colossal Biosciences stunned the world by announcing it had overseen the birth of three dire wolves, a species of oversized white wolf known to fans of Game of Thrones, but one that has been extinct in reality for over 10,000 years. They have plans to bring the woolly mammoth back to the northern tundra, and revive the dodo bird, too.

Even before this week's surprise news, executives at the Toronto Zoo have been wrestling with the ethics of "de-extinction" and the mammoth question, and Toronto Star reporter Kate Allen has been reporting on the issues that they and other zookeepers around the world, and conservation experts, see with the sudden application of this technology.

Allen joins This Matters to explain just what Colossal is doing and why it chooses pop-culture celebrity "charismatic" species to revive. And she outlines the ethical, technical and practical questions, and the massive amounts of money and scientific expertise, that this startup company has suddenly brought to the field of animal conservation.

PLUS: Did they really bring back dire wolves, or are these animals something else entirely?
