Phys.Org mentions an interesting article published in the International Journal of Osteoarchaeology. The article concerns a fragment of a whale rib, dating to the Pliocene, that shows evidence of a shark bite. In this case the rib also displays evidence of having survived the attack. From Phys.Org: (more…)
In the previous post in this series I looked at vitamin D metabolism and the effects of vitamin D deficiency on the skeleton. So, lets talk about Lubenow and Neanderthals. Lubenows discussion of Neanderthals and rickets occurs in chapter 14. He begins the chapter by invoking the Genesis flood to explain the ice ages, which only lasted, according to Lubenow, for 700 years (give or take). (more…)
I have mentioned previously that I was reading Lubenow’s Bones of Contention. In this post I would like to focus on Lubenow’s understanding of rickets and Neanderthal morphology. In order to discuss that I first need to discuss vitamin D deficiency (more…)
There is an interesting article in HOMO – Journal of Comparative Human Biology on the proximal femur. The article, Geometric morphometric analyses of hominid proximal femora: Taxonomic and phylogenetic considerations, looked at whether one can separate extant hominids into different taxa using geometric morphometrics and whether one could distinguish Homo from Australopithecus and Paranthropus. (more…)
I am going to be very busy today so I won’t get an in depth post up on Australopithecus sediba until tomorrow. In the meantime three items jumped out at me so I thought I would, briefly, mention them.

Can some one send me a copy of the following article:

I know I have mentioned this before (unfortunately, I can’t find where) but Richard Steckel and Jerome Rose (among others) are working on a fascinating project called the Global History of Health Project. One of the reasons that I brought this up is because the Jewish World review has a fascinating overview of the project: (more…)
I’ve been meaning to mention this ever since the article was published in PLoS One.
Brucellosis is an infectious disease caused by any of several bacilli. It is primarily found in livestock such as cows, horses, pigs, and goats. It has also been found in wild animals such as zebra, eland, waterbuck, and impala. It is primarily transmitted to humans via infected dairy products and meat. In humans the disease appears as a chronic infection of the lungs and recurring fevers. Males are affected more than females. The primary center of skeletal involvement occurs in the spine. Ortner and Putschar define the lesion involved as follows:
The lesion is a lytic cavitation. Grossly and on X-ray, it frequently can be seen penetrating the vertebral end-plate and extending through the nucleus pulposus of the disc into the next vertebral body … The cancellous bone within the focus is destroyed without formation of significant sequestra. The cortex also may be perforated, leading to parosteal abscesses. There is usually very little, if any, reactive bone formation except in the healing phase … In contrast to tuberculosis, which it resembles in several ways, complete collapse of vertebrae with gibbus formation is usually not observed … and paravertebral abscess is rare …
The PTC test is well known to the point of annoyance. Practically, every biological anthropology class I ever had mentioned it, as did a number of the cultural anthropology. A new article in Biology Letters – requires a subscription puts a new spin on the question.
