Cradle of Humankind
Around 2.07 million years ago, just before the arrival of "P. robustus" and "H. erectus", "A. africanus" became extinct in the Cradle of Humankind. It is possible that South Africa was a refuge for "Australopithecus" until the beginning of major climatic variability and volatility, and, perhaps, competition with "Homo" and "Paranthropus".
