Biologists establish the origin date of the earliest tetrapods and discover they acquired several of the major new adaptive traits that enabled vertebrate life on land at accelerated evolutionary ...

The skulls of tetrapods had fewer bones than extinct and living fish, limiting their evolution for millions of years, according to a latest study. Tetrapods evolved from fish and were the earliest ...

Researchers report a unique skeletal structure in the fins of a tetrapod-like fossil fish. Living four-limbed vertebrates, or tetrapods, exhibit a common skeletal pattern in the proximal part of their ...

One of the biggest questions in evolution is when and how major groups of animals first evolved. The rise of tetrapods (all limbed vertebrates) from their fish relatives marks one of the most ...

In this video segment from NOVA: "Judgment Day: Intelligent Design on Trial," paleontologist Neil Shubin recounts a fossil discovery that added another compelling piece to the body of evidence that ...

If you want to see concrete evidence of evolution, look no further than your hand or your foot. Five fingers, five toes. There's nothing magical about the number, yet five digits at the end of their ...

Newly discovered tetrapod footprints suggest that the evolution of limbed vertebrates may have occurred nearly 20 million years earlier than scientists previously believed, according to a study ...
