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 ...

Humans are one of 60,000 species that share a 500 million year old common ancestor. This creature was the ancestor of almost every vertebrate species, but it had a sixth sense that most of its ...

Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves ...

Just seven millimeters long, flea toads are among the smallest vertebrates on Earth. Despite their diminutive size, their organs and functions hardly differ from animals a thousand times larger. While ...

The fossilized skull of Coccocephalus wildi, an early ray-finned fish that swam in an estuary 319 million years ago. The fish is facing to the right, with the jaws visible in the lower right portion ...

Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn 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 ...

A new study out of the University of Chicago, the Canadian Museum of Nature and the Albany Museum challenges a long-held hypothesis that the larvae of modern lampreys are a holdover from the distant ...

Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory ...

A 319-million-year-old fossilised fish has revealed the oldest example of a well-preserved vertebrate brain, according to scientists. The preserved creature, pulled from a coal mine in England more ...
