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 ...
Scientists have long puzzled over the gap in the fossil record that would explain the evolution of invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, ...
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 ...
