The homoplastic apes
Bernard Wood and Terry Harrison have published a review paper in NatureWood:Harrison:2011, arguing that the extent of anatomical convergence among Miocene ap...
Ardipithecus challenge explication: the pelvis
The other day, I started writing about the Sarmiento-White exchange on Ardipithecus, by describing how they disagree about the implications of the molecular ...

Ann Gibbons reports on the AAPA meetings with a story about all the Homo erectus pelvis and stature papers (“Human ancestor caught in the midst of a makeover...
The Ardipithecus pelvis
One of the grottiest, most severely crushed parts of the Ardipithecus ARA-VP-6/500 skeleton is the pelvis. The left os coxa is nearly complete but badly dist...
Mrs. Elvis, the Homo erectus pelvis
Scott Simpson and colleagues describe their find of a 1.5-million-year old, relatively complete pelvis of early Homo from Gona Ethiopia. The paper is in Scie...
