Scientists have unveiled partial skeletons of the two million-year-old species Australopithecus sediba that were discovered in South Africa in 2008.
“All of the research so far shows that sediba had a mosaic of primitive traits and newer traits that suggest it was a bridge between earlier australopiths and the first humans,” said Professor Debbie Guatelli-Steinberg of Ohio State University. That is to say, the skeletons showed some traits of humans and some traits of chimpanzees.
