Researchers, including Jeff Streicher, Senior Curator in Charge, Amphibians and Reptiles at the Natural History Museum, London, have unveiled the most extensive evolutionary tree of frogs (anuran amphibians) to date. This comprehensive phylogeny, based on hundreds of genetic markers and a staggering 5,242 frog species, is set to transform our understanding of these fascinating creatures.
The study,"Frog phylogeny: a time-calibrated, species-level tree based on hundreds of loci and 5,242 species," is published inThe new research has also shifted the possible start date for when living frogs began evolving. According to Jeff Streicher, a lead author on the paper,"Previously the group was thought to have begun to split into the thousands of species we see today around 210 or 220 million years ago.
Frogs, with their diverse natural histories, have always been a subject of fascination for biologists and nature enthusiasts alike. However, previous attempts to create comprehensive phylogenies for these creatures were limited by the types of genetic data being used. In this study, researchers addressed these limitations by developing an expansive family tree that combined
