Biologists have considered nearly every major taxon of animals as the key starting point for the evolution of vertebrates. We survey these ideas, many of which are no longer tenable in the light of ...

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 ...

Scientists once thought that humans must have two million genes to account for all our complexity. But since sequencing the human genome, we've learned humans only have about 19,000 to 25,000 genes - ...
