A 1.84-million-year-old modern human hand bone has been discovered in Tanzania’s Olduvai Gorge.
Scientists have discovered the oldest known fossil of a hand bone to resemble that of a modern human, and they suggest it belonged to an unknown human relative that would have been much taller and larger than any of its contemporaries.
This new finding reveals clues about when modern humanlike hands first began appearing in the fossil record, and suggests that ancient human relatives may have been larger than previously thought, researchers say in a new study.
