Scientists discovered Homo floresiensis, a three-foot-tall human species with a brain the size of a grapefruit, on Flores Island in Indonesia; this species evolved in total isolation and lived alongside human ancestors until just 50,000 years ago, demonstrating that human evolution can occur independently in isolated environments.

Scientists found a species of tiny humans on an islandAdded:
On the island of Flores in Indonesia, scientists dug up a human that should not exist.
3 ft tall, brain the size of a grapefruit, but it made tools.
It hunted.
It used fire. [music] They called it Homo floresiensis, a completely separate species of human that evolved in total isolation on that island.
It lived alongside our ancestors until just 50,000 years ago. Recent enough that local legends still describe tiny people living in caves.
Scientists still argue about what [music] it means.
Some believe other isolated islands may hide more undiscovered human species.
We thought we were the only humans.
We were never alone.
