Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Researchers found in ...

This whale, horse, snake, and bird—though different in structure and function—are all considered tetrapods. The animals that no longer exhibit four legs are classed as tetrapods because their ...

Until Sony started shipping its Triluminos HDTVs, the future of quantum dot (QD) technology in real-world products was mostly theoretical. Now, a company called Quantum Materials has started shipping ...

It turns out that just moving into a new environment is not always enough to trigger functional adaptations. In their paper, the authors say the results may be explained by an earlier hypothesis: A ...

The relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) is well established, but the origin of major tetrapod features has remained obscure for lack of fossils that ...

Melvyn Bragg and guests discuss the great evolutionary change that gave rise to all the land animals on Earth with a backbone, when some fish developed limbs, lungs and necks. Show more Melvyn Bragg ...

Fossilized footprints found in an abandoned quarry in Poland hint that four-limbed creatures called tetrapods evolved much earlier and in a radically different environment than previously thought. The ...

Inspired by the tetrapod structures of a breakwater, a highly efficient electrocatalyst for oxygen reduction reaction (ORR) in alkaline solution has been created from low-cost, commercial melamine ...

Figure 1: Lower jaw of a Late Devonian (Famennian) ichthyostegid tetrapod from Belgium (Liège University palaeontology collection, 6106a). The Late Devonian saw an increasing faunal exchange between ...
