"It is fascinating to see direct evidence that these archaic species did exist (alongside us) and it's only for the last few tens of thousands of years that is unique in our history that we are alone on this planet and we have no close relatives with us anymore."

The form and size of the AIIS in [Ardipithecus ramidus], as well as its projection anterior to the acetabular margin, indicate that this structure had already begun to appear and mature via a novel physis (from Lovejoy et al. 2009: 71e3, emphasis mine)
What distinguishes the AIIS in hominids from those in apes is not its protuberance (those of Gorilla are often very prominent), but rather its emergence from a novel, separate physis, a hominid adaptation that is almost certainly associated with dramatic expansion of iliac isthmus breadth (Lovejoy et al. 2009b) (from Lovejoy & McCollum 2010: 3295, emphasis original)
Further it is an extraordinary occurrence that two adolescent ilia of apparently opposite sex but virtually identical age should be found in close company in this deposit. The boy [MLD 7] was killed by a bone-smashing blow on the chin from a club or fist. Were they brother and sister [MLD 25] twins, that shared in death the same cannibalistic fate? (Dart 1953: 75)
