'A completely different story': 300 million-year-old fossils reveal the first vertebrate land dwellers weren't what we thought, researchers claim
New fossil evidence suggests that early tetrapods developed directly from small versions of themselves rather than undergoing an amphibian-like tadpole stage. This discovery challenges previous assumptions about the reproductive biology of the first land-dwelling vertebrates.

It reshapes our understanding of evolutionary history and the biological strategies that allowed early vertebrates to successfully transition from water to land.
Our ancient four-legged ancestors didn't have an amphibian-like life cycle when they began walking on land, according to a new study of rare fossils found near Chicago.
