Homo rhodesiensis
Woodward, 1921

Homo rhodesiensis is the species name proposed by Arthur Smith Woodward (1921) to classify Kabwe 1 (the "Kabwe skull" or "Broken Hill skull", also "Rhodesian Man"), a Middle Stone Age fossil recovered from a cave at Broken Hill, or Kabwe, Northern Rhodesia (now Zambia).[1]. In 2020, the skull was dated to 324,000 to 274,000 years ago. Other similar older specimens also exist.[2]

Homo rhodesiensis s.s. appears to have diverged earlier than H. heidelbergensis s.s. (Mauer). H. rhodesiensis s.l. is now mostly considered a synonym of H. heidelbergensis s.l[3], or perhaps then slightly larger. Other designations such as Homo sapiens arcaicus[4] and Homo sapiens rhodesiensis[5] have also been proposed.

Fossils[edit]

Replica of the Kabwe cranium
Interpretation of "Rhodesian Men" by Amédée Forestier (1922)

A number of morphologically comparable fossil remains came to light in East Africa (Bodo, Ndutu, Eyasi, Ileret) and North Africa (Salé, Rabat, Dar-es-Soltane, Djbel Irhoud, Sidi Aberrahaman, Tighenif) during the 20th century.[6]

  • Kabwe 1, also called the Broken Hill skull, or "Rhodesian Man", was assigned by Arthur Smith Woodward in 1921 as the type specimen for Homo rhodesiensis; most contemporary scientists forego the taxon "rhodesiensis" altogether and assign it to Homo heidelbergensis.[7] The cranium was discovered in Mutwe Wa Nsofu Area in a lead and zinc mine in Broken Hill, Northern Rhodesia (now Kabwe, Zambia) on June 17, 1921[8] by Tom Zwiglaar, a Swiss miner. In addition to the cranium, an upper jaw from another individual, a sacrum, a tibia, and two femur fragments were also found.
  • Bodo cranium: The 600,000 year old[9] fossil was found in 1976 by members of an expedition led by Jon Kalb at Bodo D'ar in the Awash River valley of Ethiopia.[10] Although the skull is most similar to those of Kabwe, Woodward's nomenclature was discontinued and its discoverers attributed it to H. heidelbergensis.[11] It has features that represent a transition between Homo ergaster/erectus and Homo sapiens.[12]
  • Ndutu cranium,[13] "the hominid from Lake Ndutu" in northern Tanzania, around 600-500,000 years old[14] or 400,000 years old. In 1976 R. J. Clarke classified it as Homo erectus and it has generally been viewed that way, although points of similarity to H. sapiens have also been recognized. After comparative studies with similar finds in Africa allocation to an African subspecies of H. sapiens was considered most appropriate by Phillip Rightmire.[15] An indirect cranial capacity estimate suggests 1100 ml. Its supratoral sulcus morphology and the presence of protuberance as suggested by Rightmire "give the Nudutu occiput an appearance which is also unlike that of Homo erectus". And in a 1989 publication Clarke concluded: "It is assigned to archaic Homo sapiens on the basis of its expanded parietal and occipital regions of the brain".[16] But Stinger (1986) pointed out that a thickened iliac pillar is typical for Homo erectus.[17] In 2016, Chris Stringer classified the cranium as belonging to Homo heidelbergensis/Homo rhodesiensis (a species considered to be intermediate between Homo erectus and Homo sapiens) rather than as early H. sapiens, but considers it to display a "more sapiens-like zygomaxillary morphology" than certain other examples of Homo rhodesiensis.[18]
  • The Saldanha cranium found in 1953 in South Africa, and estimated at around 500,000 years old, was subject to at least three taxonomic revisions from 1955 to 1996.[19]
