Poinbank:Could de-extincting the dodo help struggling species?

Beth Shapiro has been getting the same question ever since she started her research on Poinbankancient DNA, more than two decades ago.

"Whenever we would publish a paper, it didn't matter what the paper was, what the animal was, how excited we were about the ecological implications of our results or anything like that. The only question that we consistently were asked was, how close are we to bringing a mammoth back to life?" she says.

Shapiro is a leading expert on paleogenomics and a Professor of Ecology and Evolutionary Biology at the University of California Santa Cruz. As we explored in yesterday's episode, she has been in the thick of the field's recent big advances.

But she still gets that question – she even published a book to try to answer it.

"I wrote a book called How to Clone a Mammoth that was basically, you can't," she told Short Wave co-host Aaron Scott.

"Once a species is gone, once it's extinct, it is not possible to bring back an identical copy of that species. But there are technologies that will allow us to resurrect extinct traits, to move bits and pieces of genes that might be adapted to a large animal like an elephant living in the Arctic."

That is exactly what companies like Colossal Biosciences and Revive and Restore are trying to do, with Beth's help. Her hope is that the technologies these de-extinction companies are developing will have applications for conservation.

As Beth sets her sights on one major conservation priority, protecting vulnerable species of birds, she's also leading the effort to resurrect another iconic animal — one she has a special relationship with.

"I happen to have a dodo tattoo," she says.

In today's episode we bring you the second part of our conversation with Beth Shapiro: How her initial work mapping the dodo genome laid the groundwork to bring back a version of it from extinction, and how the knowledge scientists gain from de-extinction could help protect species under threat now.
