The discovery by Dubois of the much discussed remains of Pithecanthropus erectus in a situation which seems to indicate for them a late Pliocene horizon, has reawakened interest in the phylogeny and antiquity of man, and has led to a reexamination of some of the more interesting prehistoric remains. The Neanderthal skeleton has recently been carefully studied by Schwalbe and Klaatsch and minute comparisons have been made with recent races on the one hand, with the Spy remains and Pithecanthropus on the other and also with the recent anthropoids.

The results of these studies have demonstrated a great similarity between the Neanderthal and Spy skeletons and the possession by these of so many peculiarities which lie beyond the limits of variation in recent human races, that it has been thought necessary to recognize them as representatives of a distinct species of Homo, the H.Neanderthaliensis. Of this species we know at least three individuals and possibly more, and it seems certain that it is quite distinct from the Pithecanthropus, the skull characters of this Javanese form placing it on a much lower level than the Neanderthal-Spy skulls, and showing a more pronounced approach toward generalized anthropoid condition than is to be seen in the European skulls. There is, however, an enormous gap between even Pithecanthropus and the recent anthropoids, and, indeed, it seems certain that the latter cannot be regarded as coming into the direct line of human descent, but both these and existing human races must trace back to a common ancestor, whose characteristics are perhaps indicated in the cranial peculiarities of young anthropoids.

If this be the case it would seem that the origin of the human race must be referred back to a period antedating considerably the horizons to which H. Neanderthaliensis and Pithecanthropus belong. The former is assigned by Klaatsch to the first interglacial period, at the close of the Chelléan era, while the latter seems to pertain to the late Pliocene, and the divergence of form which led to the genus Homo would accordingly seem to be referable to the early Pliocene or possibly even to the Miocene period.
