OUR FACE FROM FISH TO MAN 



World or catarrhine monkeys shows various stages 

 in the reduction of the pointed tip {cf. Pocock, 

 1925, Fig. 36). The ear of a six-months' human 

 foetus (Fig. 109B) figured by Schwalbe has a 

 truncate upper rim and vestigial tip and in general 

 appearance approaches the Old World monkey 

 type (Fig. 109A) as noted by Schwalbe. The un- 

 rolled outer rim and Darwin's point, found as an 

 occasional variant in man, is reminiscent rather of 

 the monkeys than of the anthropoids, although 

 indications of the Darwin's point are not lacking 

 in certain chimpanzees {cf. Hseckel, 1903, PL 26) 

 and in certain orangs (Pocock, 1925, Fig. 37D, E). 

 The ears of the great anthropoid apes, while 

 highly variable in details, are substantially of the 

 human type, especially those of the gorilla. All 

 have the rolled-over upper rim, but in the chim- 

 panzee the hinder rim, according to Pocock (1925) 

 is "sometimes flat, sometimes slightly overfolded 

 but never apparently so overfolded as is typically 

 the case in Homo. The lower lobe, varying in 

 size, is not so well developed as in Man." On the 

 whole the external ears of the gorilla and chim- 

 panzee are remarkably human in appearance and, 



like so many other features of anthropoid anatomy,
