Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!

Science Magazine @science.org · Sep 4

New findings in Science suggest that rodents owe much of their evolutionary success to their thumb-nail (the first digit, D1), an adaptation that gave them dexterous hands for cracking seeds and nuts.

This red squirrel’s hands display tiny nail-bearing thumbs, alongside large claw-bearing digits.

It's not a dire wolf. It's a gray wolf clone with 20 dire-wolf gene edits, and with some dire wolf traits. And here's my story! Gift link: www.nytimes.com/2025/04/07/s...

in case you're wondering, "what's the harm in claiming an extinct species has been brought back from the dead" when it most certainly has not, our interior secretary is already using it to justify taking animals off the endangered species list

The mission of the U.S. Fish and Wildlife Service is to work with others to “conserve, protect, and enhance fish, wildlife, plants, and their habitats for the continuing benefit of the American people.”

The Department of the Interior is excited about the potential of “de-extinction” technology and how it may serve broader purposes beyond the recovery of lost species, including strengthening biodiversity protection efforts and helping endangered or at-risk species.

The Endangered Species List has become like the Hotel California: once a species enters, they never leave. In fact, 97 percent of species that are added to the endangered list remain there. This is because the status quo is focused on regulation more than innovation.

It’s time to fundamentally change how we think about species conservation. Going forward, we must celebrate removals from the endangered list - not additions. The only thing we’d like to see go extinct is the need for an endangered species list to exist. We need to continue improving recovery efforts to make that a reality, and the marvel of “de-extinction” technology can help forge a future where populations are never at risk.

Since the dawn of our nation, it has been innovation – not regulation – that has spawned American greatness. The revival of the Dire Wolf heralds the advent of a thrilling new era of scientific wonder, showcasing how the concept of “de-extinction” can serve as a bedrock for modern species conservation.

The Dire Wolf revival carries profound cultural significance as it embodies strength and courage that is deeply encoded within the DNA of American identity and tribal heritage.

Breakthroughs of this nature will inspire leading minds and future generations of innovators to chase the impossible, capture it, and unleash its potential!

The Department of the Interior looks forward to a vibrant future full of innovation that advances core missions such as wildlife conservation.

"Two lessons: Some experiments just don’t work out. And you get what you select for — in other words, evolution usually finds the simplest solution that is available to the organism, even if you were hoping for something else."

Richard Lenski @relenski.bsky.social · Feb 21

I just posted "Some Experiments Work, and Some Don't."

It features this new paper from Paul Rainey's group, along with a *failed* experiment that Paul Sniegowski and I ran in the 1990s trying to test the same idea.
