Thumbs are cool and all, but have you ever thought about how important thumbnails are? They just might have been the key to rodents' evolutionary success. That and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪

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!
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.
