Institute d vertebrate ology and Paleoanthropology, Chinese Academy d Sciences, Beiing 100044 2. Beijing Institute d Otorhinolaryngology, Beijing 100005) Abstract: The highly projecting nasal bones of Homo erectus fom Nanjing have been believed to be the evidence for western affinities. However, an observation made in this paper shows that highly pro jecting nasal bones have not been found in the crania from Africa, Europe and West Asia during the time period of Nanjing Homo erectus or earlier times. This feature appeared much later in Africa and Europe than in Asia. The fossil evidences available cannot support the western affinities of Homo erec- tus fom Nanjing ow Key words: Homo erectus from Nanjing; Highly projecting nasal bones; Western affinities 91994-2006 China Academic Journal Electronic Publishing House. all rights reserved. hp. //w cnki nerTHE MORPHOLOGY OF NASAL BONES OF HOMO ERECTUS FROM NANJING AND THE POSSIBILITY OF GENE FLOW FROM EUROPEAN FOSSIL HOMINIDS ZHAN G Yin2yun 1 , LIU Wu1 , ZHAN G Luo2 (11 Institute of Vertebrate Paleontology and Paleoanthropology , Chinese Academy of Sciences , Beijing 100044 ; 21 Beijing Institute of Otorhinolaryngology , Beijing 100005) Abstract : The highly projecting nasal bones of Homo erectus from Nanjing have been believed to be the evidence for western affinities.
