Despite extensive study of the bone pathology (incl. periosteal reaction & cortical bone thickening) on the 1.6 Ma H.erectus partial skeleton ER-1808, there is still no consensus on the cause of pathogenesis.
This Master’s thesis employed a more holistic approach than those taken previously,
it utilized evidence from Plio-Pleistocene archaeology, paleo-enviornmental studies & genetics, to infer the cause of the bone pathology.
Previous studieshave diagnosed ER-1808 as having hyper-vit.A (Walker cs 1982), Treponema pertenue (yaws, Rothschild cs 1995) & sickle-cell anemia (Jefferson 2004):
- peri-osteal reaction & cortical bone thickening for hypervit.A,
- gummatous lesions, frontal bone esions, periosteal reaction, tibial bowing & periosteal reaction for yaws,
- periosteal reaction, cortical bone thickening & tibial bowing for SC-anemia.
Synthesizing the literature about multiple aspects of the early-Pleistocene & from gross analysis of casts, X-rays & photographs of ER-1808 & the proposed diseases provides ample evidence to refute yaws & SC-anemia.
Hypervit.A cannot be excluded or corroborated, based on this research: the skeletal sample size is small & inaccessible.
ER-1808 postcrania do not show any of the hallmark features of a treponemal infection or SC-anemia.
Rothschild cs (1995) should not have provided a Treponema specific diagnosis: it is ill-advised to do so based on 1 partial skeleton or bone (Hackett 1976, Ortner & Putschar 1981, Webb 1995, Meyer cs 2002).
ER-1808 only shows peri-osteal reaction & cortical bone thickening, which do not warrant a diagnosis for a treponemal infection or SC-anemia.
ER 1808's climate is not conducive to yaws: she lived in an arid & dry climate + little rain, and she lived mostly through drought.
Genetics also refutes a treponemal infection or SC-anemia (Harper cs 2008, de Melo cs 2010, Liu cs 2010).
This research is significant:
it updates the paleo-pathological & PA literature + new data from genetics & paleo-enviornmental studies, to refute the yaws & SC-anemia diagnosis for ER-1808.
