Paddy K is hosting the 78th Four Stone Hearth Anthropology Blog Carnival, and the theme is Bones.
I was particularly interested by Adhominin’s look at mid Pleistocene Heidelbergensis.
At the conference, much attention was focused on the Middle Pleistocene “muddle in the middle” , particularly the role of Homo heidelbergensis in hominin evolution. While H. heidelbergensis possesses both archaic and derived traits intermediate between H. erectus and later members of the Homo genus, it lacks uniquely derived traits or autapomorphies, which are a prerequisite for defining a species.
H. heidelbergensis has traits that have been interpreted as nascent Neandertal autapomorphies, leading some researchers to propose that there was a continuous evolution of Neandertals [4-6]. This accretion model would make H. heidelbergensis a chronospecies on the continuum of the Neandertal lineage, a view championed by Jean-Jacques Hublin. The accretion model proposes that Neandertals evolved by anagenesis, i.e. non-branching evolutionary change.
