A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems.

In DNA, retrotransposons can move around and insert themselves into other parts of genomes with a kind of copy and paste mechanism. Most have lost this ability in humans, but they still make up a ...
