De-Extinction: A Scientist’s Perspective from Inside a Cloning Lab

April 1, 2026·58 min·4 clips
A living, endangered elephant species is already storing measurable extra carbon in forests, just by eating and walking.
Chris opens solo because Angel is away. He says the timing gave him a chance to finally dig into de-extinction. He lays out the basic questions right away: what it is, what gets in the way, and what it could mean for conservation. He recalls a Texas A&M wildlife-center visit that deepened his interest in wildlife work. He says he would love to clone a mammoth, but he does not think we should. From there, he draws a hard line between true cloning and newer projects people hype online. A supposed dire wolf comeback is explained as modern wolves whose DNA has been edited to resemble the old animal. That is not cloning. Cloning needs an intact somatic cell with perfect DNA, and dead animals do not leave that behind for long. Cell membranes rupture and DNA starts breaking down almost immediately, so within hours to days the genetic material is too fragmented to use. That is why mammoths, dire wolves, and woolly rhinos are not realistic cloning candidates. The episode then shifts to the species where cloning can still matter today. Recent extinctions and brink-of-extinction cases can still have preserved cells that survive the process. The northern white rhino becomes the clearest example, with just two females left; Chris points to cloning them and using southern white rhinos as surrogates to rebuild a herd. He is frank that this is less glamorous than a mammoth headline, and he is also frank that it could matter a lot more. The ibex case gives him a true cloning example, even if the animal died 15 minutes after birth. Everything lands on one clean idea: conservation now matters more than fantasy resurrection later.

As heard by us

De-extinction is treated as conservation first, not spectacle.

The piece treats de-extinction as a conservation question, not a parlor trick. Chris draws a clean line between cloning and gene editing: mammoth and dire wolf material is too broken up for cloning, since there are no intact cells or perfect DNA to work with.
