Ancient footprints mistakenly attributed to bears were made by early humans
A new look at nearly 3.7-million-year-old fossil footprints uncovered in Tanzania shows that multiple species of early humans lived together at the same time.
The early humans who walked the earth nearly 3.7 million years ago were not walking alone. Fossil footprints in Tanzania reveal that two human species once lived in the same place at the same time.
Scientists had long thought that one set of unusual prints there was left by a bear walking on its hind legs, but a new published in the journal Nature suggests that's not right. Instead, it appears that the tracks were left by some unknown early human species that was strolling around that spot at the exact same time as â the species of the famous partial skeleton "."
