European and Northwest African Middle Pleistocene Hominids

Abstract

European and Northwest African Middle Pleistocene Hominids by F. Clark Howell of human skeletal remains from the Middle Pleistocene has always been one of the greatest gaps in human-paleontological knowledge. At THE SPARSE REPRESENTATION first, Southeastern Asia was unique in having provided remains from the Trinil beds in Java, but the signifi­ cance of this poorly preserved skull-cap was confirmed and greatly amplified by subsequent discoveries (Von Koenigswald 1940) of better preserved specimens at other localities of similar age, as well as in the still older Djetis beds. Still tfuly unique in all the world is the somewhat younger occupation site of Locality 1 Choukoutien, with its extraordinarily abundant, prob­ ably cannibalized, human remains in association with hearths, stone implements (Choukoutienian chopper/ chopping-tool complex), and remains of slaughtered animals. For many years, the only such find from the West was the enigmatic human mandible from the Grafenrain gravel pit at Mauer in the Rhineland. Then, within a few years in the mid-thirties, three additional speci­ mens came to light in western Europe (Steinheim), Britain (Swanscombe), and northwest Africa (Rabat, Morocco). In the last several years, further Middle Pleistocene human remains were found in northwest Africa, both in Algeria (Ternifine) and in Morocco (Sidi Abderrahman). All these discoveries (Fig. I) have excellent paleontological associations, and, in three cases (Swanscombe, Ternifine, Sidi Abderrahman), there are associated stone implements (Acheulean of various stages). However, no occupation site is yet F. CLARK HOWELL is Associate Professor of Anthropology, De­ partment of Anthropology, University of Chicago (Chicago, Illinois, U.S.A.). He was born in 1925, and educated at the University of Chicago (Ph.D., 1953). HOWELL has undertaken field and other studies on early man in Europe (1953,1956) and in Africa (1954,1957-58,1959), and made a recent brief visit to Israel (1959). He has published various papers on human paleontology, especially as regards the Neanderthal problem, and on early man and the Pleisto­ cene in general. Prior to submitting the present paper to CURRENT ANTHRO­ POLOGY, HOWELL sent it, for comment and criticism, to three colleagues, of whom W. W. Howells and Kenneth P. Oakley responded. The response was primarily commendatory, and except for HOWELL's addition of some paragraphs along lines recommended by Oakley, the paper stands as first written. Vol. I . No.3' Ma)' 1960 known from the Middle Pleistocene of Europe or Africa with in situ human skeletal remains, stone im· plements, and the bones of slaughtered animals. These human skeletal remains, taken in conjunction with those from the Middle Pleistocene of eastern and southern Asia, have an important bearing on interpre­ tations of the course of human evolution. The signifi­ cance of these discoveries has been obscured by the pre­ occupation of some human paleontologists with other human remains either suspected to be of Pleistocene antiquity or questionable due to an extraordinary com· plex of morphological features (the famous hoax of Piltdown). Largely as a consequence of this, there have grown up two main interpretations of man's phylogeny in the Pleistocene, one depending on the possible im­ portance of the suspicious fossils, and the other de­ pending only on the scanty, but well-dated, human fos­ sils enumerated above. The former interpretation recognizes an early, at least earlier, Middle Pleistocene separation of a morphologically modern (sapiens) lineage. The latter postulates progressive transforma· tion of primitive and variable Middle Pleistocene hu­ man populations into diverse Neanderthal and re­ lated, geographically distinctive, groups, as well as into incipiently sapiens peoples. The purpose of this paper is to discuss tI-1e significance of the :Middle Pleistocene human remains from Europe and North Africa for the resolution of this basic problem in the study of human phylogeny. COMPARATIVE STRATIGRAPHY AND ASSOCIATIONS THAMES RIVER: SWANSCOl\'IBE The Swanscombe human remains were recovered from gravel deposits exposed in the Barnfield pit, be­ tween Dartford and Gravesend, on the south bank of the lower Thames River valley. Marston (1937) dis­ covered a complete occipital in June, 1935, and a left parietal in March, 1936. Twenty years later Wymer re­ covered the right parietal of the same individual. The three fragments occurred in the same seam of sandy
