The Amazon molly — a sex-skipping fish — hacks evolution
The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

A koala population’s rapid rebound may let it escape inbreeding’s perils
As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.
