A human, an octopus, and a coral may appear to have almost nothing in common, but their chromosomes still contain recognizable fragments inherited from an animal ancestor that lived more than 600 million years ago.

Since that time, chromosomes have repeatedly fused, separated, and been rearranged as new animal lineages emerged.
