In South Africa, scientists found bones in a cave they say are a new kind of early human ancestor. Those ancestors lived more than 2 million years ago. The people who found it named it Homo naledi, but it is not a direct ancestor of modern-day people. This is also the 40th anniversary of the discovery of Lucy. At 3.2 million years old, Lucy was the oldest human ancestor found at the time. She was found in Ethiopia.
