Summary

Human bone histology shows osteon size (On.Ar) varies within individuals, not between sexes or ages. Femoral osteons are larger than rib osteons, suggesting ribs are better for studying ancient human populations.

Area of Science:

  • Paleoanthropology
  • Human Osteology
  • Bone Histology

Background:

  • Investigating histological variations in human cortical bone is crucial for understanding population differences.
  • Previous studies suggest potential differences in osteon size (On.Ar) in Late Pleistocene human populations.

Purpose of the Study:

  • To explore the distributional characteristics of total osteon area (On.Ar) and Haversian canal area (H.Ar) in human bone samples.
  • To determine variations in these histological features within individual skeletons, among populations, and between sexes and ages.

Main Methods:

  • Analysis of osteon area (On.Ar) and Haversian canal area (H.Ar) from rib and femur samples of historically known individuals.
  • Data collected from three distinct populations: 18th-century Huguenots (England), 19th-century British settlers (Canada), and 20th-century South Africans.

Main Results:

  • Neither On.Ar nor H.Ar were normally distributed; approximately 96% of variation occurred within individual bone samples.
  • No significant differences in On.Ar or H.Ar were found between sexes or, generally, with age.
  • Femoral osteons were significantly larger than rib osteons across all samples. Haversian canal area exhibited high variability, particularly in the 20th-century sample.

Conclusions:

  • Late Pleistocene long bone samples show On.Ar values falling below the range of modern variation, suggesting potential differences.
  • Ribs are recommended as a preferable site for future comparative studies due to their smaller cross-sectional areas and more consistent On.Ar values.
