Bone histomorphology of the Dederiyeh Neanderthal child

摘要: To clarify bone formation and growth in Neanderthal children, we prepared a femoral midshaft cross-section of the Dederiyeh 1 child (ca. 2 years old) discovered Syria, compared its histomorphology with that modern children aged 0–6 years. Bone histomorphometry was performed regard to six parameters, i.e. cortical width, percent osteonal bone, osteon population density, non-Haversian canal secondary area, Haversian area. had thick similar mean 5–6 years, advanced formation, which represented by greater density than 2-year-old children. However, primary configuration scarcely differed between 1- 2-year-olds. The femur can be characterized as complex features seen at different ages, suggests from A variety causes, such mechanical loading, genetic control, abnormal metabolism, are plausible, but it is not possible determine these factors most affected 1.
