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 ...

A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life – driven by a ring of ...

Researchers at the University of Arizona say there may be at least twice as many vertebrate species as previously recognized. The findings suggest that global vertebrate biodiversity has been ...

"In vertebrate examples of life-long growth as fishes and amphibians – such stem cells supply the eye with fresh retinal neurons while the animal develops," explains senior author Florian Raible, ...

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 ...
