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 conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

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 ...

"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, ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light ...
