First let us consider the implements discovered by Benjamin Harrison on the Kent Plateau. For the sake of the discussion that follows, let us set aside all the evidence for stone tool industries in the Miocene and earlier geological periods (see for example, Sections 4.1–4, 4.7, 5.5), and let us consider just the Kent Plateau implements. The reasoning behind this approach is as follows. If we take seriously the evidence for the presence of toolmaking beings in Europe during the Miocene period, then the whole story of human evolution currently accepted, with the
We have seen that the eoliths of the Kent Plateau may be referred to the Pliocene period in England. The end of the Pliocene is generally placed at about 2 million years ago, although some place it at about 1.6 million years ago (Gowlett 1984, p. 200). Hugo Obermaier, one of the important scientists working in the field of paleoanthropology during the early twentieth century, wrote of “the eoliths from the chalk plateau of Kent in southern England, which belong to the Middle Pliocene” (1924, p. 8).
A Middle Pliocene date would make the eoliths of Kent 3–4 million years old. Most paleoanthropologists now put the origin of
Just for the sake of argument, let us suppose that the eoliths of the Kent Plateau can be referred to the very latest Pliocene, at about 2 million years b.p. This is, of course, too early for
Up to now, we have been speaking of the standard evolutionary account of human origins, with the major transitions taking place in Africa. But there is a second, less widely held version of the human evolutionary process. According to this account, the transition to
One would thus have to make relatively few changes in current theory to accommodate the Harrison eoliths. But once such evidence has been condemned, it must apparently remain so perpetually, with no chance of rehabilitation. Even scientists whose theories the tainted evidence might support ignore it. Why? Perhaps because if some relatively benign evidence of this kind were to be resurrected, then more threatening evidence might also emerge from the crypt.
