The new-human discovery implies that there was a wave of human migration out of Africa, the birthplace of humanity, that was completely unknown to science.
"We think Homo erectus"—an upright-walking but small-brained early human, or hominid—"was the first [hominid] to leave Africa two million years ago," Brown explained. After that the record went blank until about 500,000 years ago, until now.
"This hominid seems to have left about a million years ago, so it fills in a bit of a gap," he said.
Researchers will try to extract nuclear DNA from the bone, which carries more information than mitochondrial DNA. Link
