This Fish Has Cloned Itself for 100,000 Years. Scientists Just Figured Out How.

This fish has cloned itself for 100,000 years. Scientists just figured out how.

Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would otherwise plague a self-cloning species.

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 genetic trick helps this all-female fish species escape evolutionary doom

The Amazon molly, which reproduces asexually, has survived—and thrived—at least 10 times longer than predicted by evolutionary theory

How an all-female fish species defies evolutionary expectations

Asexual reproduction should be an evolutionary dead end. A study of asexual fish shows that a genetic ‘copy and paste’ helps to overcome the predicted costs of asexuality.
