Fossil study challenges assumption that early land vertebrates underwent amphibian-like metamorphosis
By
Jay Bennett
Summary
New fossil evidence challenges the long-held assumption that early land vertebrates underwent amphibian-like metamorphosis. Researchers studying hatchlings of three species from about 308 million years ago found that these early tetrapods emerged from eggs looking like miniature adults, without a distinct larval stage. This discovery, published in Science, overturns a textbook assumption about how vertebrates first transitioned from water to land.
