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 ...
"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, ...
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 ...
