A New Fossil Discovery Just Rewrote 150 Years of Evolutionary Theory
A recent study published in Science Advances challenges long-held evolutionary theories by suggesting that the earliest land-walking vertebrates, dating back over 300 million years, did not undergo metamorphosis. Researchers from the Field Museum of Natural History examined rare fossils of early tetrapod hatchlings, finding no evidence of a distinct larval phase like that seen in modern amphibians. This discovery implies that these ancient creatures hatched as miniature versions of their adult forms, directly contradicting previous assumptions about their life cycle and rewriting a significant chapter of vertebrate evolutionary history.
