Scientific evidence indicates that Homo erectus were the first hominids to leave Africa. Which of the following would make this conclusion incorrect? DNA analysis showing Homo erectus and modern humans did not have a common evolutionary ancestor An archaeological dig finding fossil remains of Australopithecus Africanus in Europe and Asia Finding tools used by Homo erectus in continents other than Africa A discovery of fossils of Homo erectus showing that they walked upright

The right answer is "An archeological dig finding fossil remains of Australopithecus Africanus in Europe and Asia". Homo erectus temporal range is, according to the Institute of Human Origins, 1.8 million to 50,000 years ago. The Australopithecus Africanus however was on our planet before that, 3 to 2 million years ago. So if a fossil specimen of Australopithecus Africanus was to be found in any place of Europe or Asia, the theory which assures that Homo erectus was the first hominid to leave Africa would then be invalid.
