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 ...

Bad news for fake pearls

(Phys.org) —For the first time, a group of researchers has succeeded in isolating DNA from pearls and used their genetic material to identify the specific species of oyster that produced the pearl. In a parallel project, ...
