300-Million-Year-Old Fossil Babies Challenge the Textbook Story of Life’s Move Onto Land
Fossils of young tetrapods suggest that the common ancestors of amphibians, reptiles and mammals did not evolve from animals with tadpole-like larvae, as scientists once thought. The first animals to move from water onto land may not have grown up the way scientists long assumed. For decades, the standard picture was that early tetrapods, the [...]
Researchers have discovered new fossil evidence that challenges the traditional narrative about the evolution of vertebrates that migrated from water to land. The study, published in the journal Science, reveals that the embryos of primitive tetrapods, known as embolomeres, did not undergo the metamorphosis stage typical of modern amphibians. New evidence about tetrapods The fossils of embolomeres embryos, found in Mazon Creek, indicate that the…
