[Taxacom] primate external ear

[John Grehan]

For those of you interested in keeping tabs on the latest developments
with the orangutan evidence for hominid origins, I now have further
corroboration of the unique anatomical similarity of the orangutan and
human external ears now that I have a high resolution image of a gibbon
ear (http://www.sciencebuff.org/externalear.php). The gibbon ear
(Hylobates lar, and agilis) show that they, like perhaps all other
primates, have a relatively broad separation of the inner and outer
helix. In addition the gibbons show the transverse convex bar between
inner and outer helix that is otherwise only found in gorillas and some
chimpanzees. I am now willing to bet the human-orangutan similarity
represents another will corroborated uniquely shared character that
supports (along with at least about 30 other characters) a unique common
ancestor.
