The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...
Most people don’t think of turtles as being exceptionally chatty—or even making sounds at all. But research published today in Nature Communicationsreveals that at least 50 turtle species vocalize—and ...

There may be twice as many vertebrate species on Earth as thought, thanks to hidden cryptic species
“We found that cryptic species are consistently widespread and common across major vertebrate groups. In every major group of vertebrates, we estimated (on average) approximately two cryptic species ...
Living sharks are often portrayed as the apex predators of the marine realm. Paleontologists have been able to identify fossils of their extinct ancestors that date back hundreds of millions of years ...
About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, and shallow seas shrank fast. Ocean chemistry also shifted hard. In what ...
Earth’s vertebrate diversity may be far richer than anyone realized. A sweeping analysis of more than 300 studies suggests that for every known fish, bird, reptile, amphibian, or mammal species, there ...
Direct survival benefits in larger groups rather than kin-selected indirect fitness primarily drive the evolution of division of labor in cooperatively breeding vertebrates, particularly under harsh ...
