. Adventures with animals and plants. Biology. 568 The Earth and Its Inhabitants Change unit x do speak of a Rhodesimi man {Hovio rhodesiensis), known from a well-pre- served skull found in South Africa. This skull is interesting because it shows that this man suffered from decayed teeth. Some parts of the skull seem to indicate that he was primitive; other parts are so much like modern skulls that he is classi- fied in the genus Homo. We cannot date him. One unusual fossil uncovered near Heidelberg in Germany is known as Heidelberg man {Hovio heidelbergeii- sis). A single jaw bone is all that has been found, and no tools of any kind. But this jaw bone tells the expert a good deal. It is a thick, massive jaw like those of primitive forms ^vith sixteen solidly rooted teeth. These resemble our teeth closely; they are without doubt human teeth. Judging from the animal fossils found in the same deposits, Heidelberg man may have lived as much as three quarters of a million years ago (at three o'clock). But so modern are the teeth that he is placed in the genus Homo, though not in the species Homo sapiens. Thus we find a form belonging to the genus Homo living, it seems, about three quarters of a million years ago, long be- fore the Java ape men and Peking men. Neandertal men. Much later than the primitive Java ape men and Peking men came Neandertal (nee-an'der-tall) men {Homo nemiderthalensis). The earliest of these men appeared about 150,000 years ago (roughly at about nine o'clock on the face of the clock shown in Figure 518. These men are well known to sci- entists, for more than one hundred skulls or other bones have been found. Even complete skeletons have been discovered. Enter Homo sapiens Heidelberg mar> may have Neandertal man appears appeared at this time. Peking man '^ ^Java man Fig. 518 If the first TiiavUke for?}7s appeared at 12 noon on the clock, /,ooo,uoo years ago, what happened at 5, at 6, at 9, and at nearly niid- night? Only the hour hand is show?!
