How are hybridized species affecting wildlife?

Researchers who transplanted combinations of wild, domesticated, and domesticated-wild hybridized populations of a fish species to new environments found that within 5 to 11 generations, selection could remove introduced ...

Coming soon: Genetically edited fruit?

Recent advances that allow the precise editing of genomes now raise the possibility that fruit and other crops might be genetically improved without the need to introduce foreign genes, according to researchers writing in ...

Delegating the dirty work is a key to evolution

We have hundreds of types of cells in our bodies – everything from red blood cells to hair follicles to neurons. But why can't most of them create offspring for us?

Fly dreams and the boundaries of evolutionary science

In 2002, Secretary of state Donald Rumsfeld made a statement regarding weapons of mass destruction that today is still well known. He famously parsed the evidence (or lack thereof) into "known knowns, known unknowns, and ...

Environment drives genetics in 'Evolution Canyon'

Interplay between genes and the environment has been pondered at least since the phrase "nature versus nurture" was coined in the mid-1800s. But until the arrival of modern genomic sequencing tools, it was hard to measure ...

Evolution of new species requires few genetic changes

Only a few genetic changes are needed to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately ...
