Origin of the vertebrate dentition : teeth transform jaws into a biting force / Moya Meredith Smith and Zerina Johanson -- Flexible fins and fin rays as key transformations in ray-finned fishes / ...

Pterosaurs originated in the Late Triassic as the first vertebrates to achieve powered flight, initiating more than 150 million years of evolutionary experimentation. Early forms retained long tails ...

Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions ...

Scientists have generated the genome assemblies of two hidden-neck turtles, unpublished until now. The results, which revealed a new three-dimensional structure of the genome within the phylogenetic ...

A harlequin poison dart frog (Oophaga sylvatica) is pictured at the Tesoros de Colombia (Treasures of Colombia) sustainable farm in Nocaima, Cundinamarca department, Colombia, on July 9, 2024.

Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured ...

The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

Visual pigments are the molecular basis of photoreception in vertebrates, comprising opsin proteins bound to light-absorbing chromophores. These pigments evolved through successive rounds of gene ...

The water-to-land transition stands as one of the most significant events in vertebrate evolution, giving rise to the two major groups of living land vertebrates-amniotes and lissamphibians-which ...

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...
