Evolutionary offshoot. This prominent ridge along the top of the skull of Paranthropus aethiopicus was for anchoring its strong jaw muscles. A heavy jaw and big teeth probably enabled it to chew tough, woody plants. Living in Kenya between 2.3-2.7 million years ago, it may have been an ancestor of the robust australopithecines. These creatures were an evolutionary offshoot that probably died out due to environmental change or competition by the newly evolving human species.
