  was here that startling discoveries of human remains were found in 1921, 1923 and 1927. The early finds were no more than three teeth but these were to be the cause of great interest as they clearly came from a species of man that had not been found before and they were the first evidence of early human habitation in China during the Paleolithic Age.

  On December 2nd 1929 a complete skullcap was discovered and this proved the theory that was derived from the earlier finds of the teeth. This was in fact the proof of existence of a humanoid species dating from between 700,000 and 200,000 years ago.

  This initial find was to lead to other discoveries of skeletal remains and from these it was possible to deduce that what became known to the World as Peking Man or Sinanthropus pekinensis was in fact in bodily form virtually identical to modern man. The difference is in the shape and construction of the skull demonstrating what had been found was a hitherto entirely unknown hominid genus and species.

  The skull has a low forehead with a protruding supra-orbital bone [eyebrow]. The occipital bone at the back of the head is sharply angled and there is a large and powerful jaw. The teeth are distinctly human but these are quite large. Importantly, the canine teeth do not overlap, as is the case in apes. Overall, the average cranial capacity was found to be approximately 80 per cent of that of the average modern man confirming a somewhat smaller brain.

  Measurement of the femurs found shows that the average height of a male was some 156 cm and a female was 144 cm. The bones indicated that the life span of Peking Man was short and that probably 68.9% died before the age of 14 years while only 4.5% lived to the age of 50 years.

However, other finds which included ashes and bones show that these people used fire for cooking food and the provision of light, warmth and protection from wild beasts. Tools made from bones and sharpened stones indicate a fairly well established culture. Close by the Peking Man site but further up the mountainside three complete adult skulls were discovered. These have been attributed to what is now called Upper Cave Man. Here the important finds included bone needles, animal teeth that had been
