SCIENCE PROGRESS 



Woodward founds his new genus mainly upon the form of 

 the mandibular symphysis, which he contrasts with that of the 

 three species of Homo. The contrast in this respect between 

 Eoanthropus and heidelbergensis is, however, less striking than 

 Woodward seems to imply, for there is a clear vestige of the 

 flange in the Heidelberg jaw, and in the latter, as in the 

 Piltdown mandible, the genio-hyo-glossal and genio-hyoid 

 originate in a pit. In fact, as Prof. Sollas has well remarked, 

 in the structure of its symphysis the Heidelberg jaw "stands

midway between man and the anthropoid apes," and therefore 

 midway between sapiens and E. dawsoni. As regards date, 

 there is little reason to doubt that Dawson is right in believing 

 that the Piltdown skull is contemporaneous with the Paleolithic 

 implements which were found near it. These implements are 

 late Chellean or early Acheulean. It is certainly remarkable 

 that a creature with such a simian jaw should have been living 

 in Chellean times, but it is probable, as Woodward suggests, 

 that the representatives of the Piltdown race living in what is 

 now Britain were a surviving remnant of a very ancient stock.
