Human to fish, and back again: a brisk walk through our evolutionary history

Via stints as reptiles, rodents and fish with feet, the evolution of humans is as meandering as it is extraordinary. Reminiscent of a similar sequence from Carl Sagan’s iconic TV series Cosmos (1980), this short animation traces human evolutionary history back 550 million years to a small, primitive fish known as Metaspriggina, believed to be an early ancestor of all living vertebrates. The result is an enlightening overview, not only of our own curious lineage, but of the unpredictable turns that evolution can take for all species.
