Their work provides more evidence that even early in our evolutionary journey, our Homo ancestors weren’t confined to warm African lowlands.
Archaeologists are rewriting the story of an early human child whose fossilized jaw and impacted teeth were discovered more than 40 years ago in the Ethiopian highlands. Scientists used high-tech imaging to reveal that early humans, apparently Homo erectus, inhabited this high-altitude plateau two million years ago. Their work provides more evidence that even early in our evolutionary journey, our Homo ancestors weren’t confined to warm African lowlands. Instead, they took advantage of a variety of diverse environments—a precursor of their ability to subsequently spread out across the prehistoric world.
