For millions of years, life remained connected to water before some animals made the incredible journey onto land. The first four-legged creatures, known as tetrapods, eventually gave rise to today’s mammals, birds, reptiles, and amphibians.
Scientists believed these early land animals developed much like modern amphibians, beginning life as tadpole-like creatures before transforming into adults. But a new fossil discovery has challenged that long-standing idea. Tiny fossilized babies of ancient crocodile-like predators suggest the earliest tetrapods may have grown in a completely different way than researchers once imagined, as per a report by Phys Org.
