California two-spot octopuses learned to track prey they could see only as a mirror reflection, then moved toward the actual ...

Whole-genome duplications are rare evolutionary events in which all the chromosomes and genes of a species are doubled. This supplies new genetic material to the gene pool and can provide an ...

The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They ...

New research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode ...

ABOUT 370m years ago, in the latter part of the Devonian period, the ancestor of all land vertebrates stepped out of the ocean and began to take advantage of the untapped riches found ashore. This was ...

A team of herpetologists at the Universidade Estadual de Santa Cruz just reported that a tiny frog found only in a hilltop forest in southern Bahia, Brazil, may be the smallest vertebrate in the world ...

New CU Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an ...

Scientists have long puzzled over the gap in the fossil record that would explain the evolution of invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, ...

Charles Darwin proposed that evolution is driven by gradual variations in organisms that have a survival advantage in a changing environment. But University of Maryland evolutionary biologist Karen ...

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 ...

In the limestone ranges of Western Australia’s Kimberley region, near the town of Fitzroy Crossing, you’ll find one of the world’s best-preserved ancient reef complexes. Here lie the remnants of ...
