This is my reconstruction of a hominin specimen known as Kabwe 1, named for the town of Kabwe, Zambia near which it was found. Dating back between 324,000 and 274,000 years ago during the Middle Pleistocene, this specimen was originally classified as a novel species called Homo rhodesiensis, but that taxon has since become a junior synonym of Homo heidelbergensis.
What is remarkable about Kabwe 1’s skull is that, although its prominent brow ridges and low braincase profile appear “archaic” (i.e. inherited from earlier hominins), its braincase volume of 1,230 cubic centimeters overlaps with the range seen in modern humans.
