See https://www.livescience.com/oldest-homo-erectus-fossil-dremolen.html and https://en.wikipedia.org/wiki/Homo_erectus regarding Homo erectus. The last paragraph of the Live Science article says the following. "Because fossil remains of Australopithecus and Paranthropus found at Drimolen date to the same time period, this research suggests the three archaic hominins all lived side-by-side in southern Africa at the same time — albeit briefly. This era would have been a moment of transition, the researchers wrote, right before Australopithecus went extinct and Homo erectus was just beginning its nearly 2 million-year residency on Earth. Indeed, the authors concluded, it could be that fierce competition with Homo erectus and Paranthropus finally led to the demise of Australopithecus — a possibility never seriously considered until now."
The Wikipedia article says the following. "Homo erectus (/ˌhoʊmoʊ əˈrɛktəs/; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2 million years ago.[2] Its specimens are among the first recognizable members of the genus Homo."
