Earth—including the dinosaurs—that these crafty amphibians were able to make their big evolutionary move, according to new research. A study published in Proceedings of the National Academy of Sciences this week shows that frog populations exploded after the Cretaceous- Paleogene extinction event some 6. When a large asteroid struck the Yucatan Peninsula some 6. Earth, including nearly every animal larger than 5. With the giant lizards suddenly gone, and as the environment slowly healed itself, the survivors jockeyed for position within the re- emerging ecosystems. ![]() Download extra podcasts and articles for offline listening or reading, bring more than one book, and consider backup like a battery case or external battery pack to. New research from the Florida Museum of Natural History and Sun Yat- Sen University in Guangzhou, China, shows that frogs were among the greatest beneficiaries of the transition from the Late Cretaceous to the post- dinosaur Paleogene. In an effort to learn more about frog evolution, researchers David Blackburn and Peng Zhang put together a new phylogenetic tree of these amphibians (phylogenetic trees are like family trees, but at the species level, and driven by genetic data) . The researchers looked at 9. DNA of 1. 56 frog species to establish genetic relationships and develop evolutionary timelines. Contrary to conventional thinking, Blackburn and Zhang found that most modern frog families didn’t originate during the Mesozoic era—that vast expanse of time during which the dinosaurs reigned. Frogs first emerged hundreds of millions of years ago, but it wasn’t until after the demise of the dinosaurs that their populations really took off. With their lizard cousins gone, frogs became among the most diverse groups of vertebrates, accounting for more than 6,7. As the new research shows, 8. Cretaceous to the Paleogene. Repressed for millions of years, these wiley amphibians were suddenly able to occupy and thrive within vacant ecological niches. The asteroid that struck the Earth, and ensuing environmental changes, destroyed a significant fraction of our planet’s vegetation, but as forests recovered, frogs were one of the many animals groups (mammals included) that were able to take advantage of the new habitats. The sixth mass extinction—the one that seven billion humans are doing their darnedest to trigger at . Frogs are threatened like never before, owing to habitat loss, pollution, disease, and other factors. According to the IUCN, nearly one- third of the world’s amphibians are now threatened or have recently become extinct. Frogs managed to survive the dinosaur era, but they’re having a hell of time dealing with us humans. Usage Statistics for communitygaze. January 2. 01. 7. Summary Period: January 2. Search String.
