Heidelberg was not found with or near any stone tools. He seems to belong to that part of the Pleistocene in which the Abbevillian tools were made. Although he shares a few physical traits with Neanderthal man, who lived much later and made excellent tools, some specialists point out that the Heidelberg jaw bears an even closer resemblance to the early man-apes of South Africa, who had no toolmaking tradition. For the long, cool, and somewhat arid second interglacial period, we have two good prospects, both probably females. One of these is from Swanscombe. In 1936, A. T. Marston found there among the undisturbed Middle Gravels a fragment of fossil skull. Except for its unusual thickness, it was not unlike an equivalent portion in the skull of modern man. Marston’s discovery was all the more exciting since this fragment fitted very well with another, obviously from the same skull, which he had found in place the previous year, only a few paces away. The two pieces, from the left side and back of the skull, provided the earliest undisputed evidence for a very early form of modern man. Twenty years later, in 1955, Mr. J. Wymer recovered a third fragment, from the right side of the same skull. The spots from which the three fragments of the Swanscombe skull were recovered mark a triangle, the sides of which measure 24, 49, and 51 feet. Near the Swanscombe bones and at the same level were found more than two hundred stone flakes as well as four small hand axes of Acheulean type, a stone knife, and fragments of other tools. As we have mentioned, the gravels appear to be an undisturbed deposit. Accordingly, they are now adequately protected and the object of a most intensive and careful excavation. From them may come yet more information about this ancient ancestor.[11] This is early man, indeed. Swanscombe, from all the evidence now available, is very close physically to modern man, closer than many fossil men from the third interglacial period. And judging from the accompanying stone tools, we may say that Swanscombe was culturally as well as physically human. Until additional remains of Swanscombe are recovered, we cannot with certainty assign these remains to a precise place among man’s ancestors. There are a few who suspect that the facial bones, should these be recovered, would place Swanscombe closer to Neanderthal than to modern man. However profitless such a conjecture may seem, it is at least suggested by our third early European fossil, the Steinheim skull.
