About This Book

A meticulous case study describes an unusual bilateral division of the parietal bones in a chimpanzee skull, documenting the exact courses, overlaps, and serration of the anomalous sutures alongside detailed cranial measurements and suture patency. The author compares these oblique divisions with previously reported parietal sutures in other apes, notes associated bends in the coronal suture and overall cranial symmetry, and records dental and vault features. Precise anatomical observations are used to consider developmental interpretations of the divisions, treating them as segmental variants of parietal formation rather than signs of traumatic or pathological alteration.

About the Author

Aleš Hrdlička

Aleš Hrdlička was a prominent anthropologist known for his contributions to physical anthropology and his studies of human evolution. He conducted significant research in various regions, including Alaska, and focused on the anthropology of Native American populations, particularly the Lenape or Delawares. His notable works include "A Bilateral Division of the Parietal Bone in a Chimpanzee," which explores anatomical variations, and "Anthropological Survey in Alaska," which provides insights into the indigenous cultures of the region. Hrdlička's research has been influential in the field, helping to shape the understanding of human biological diversity.
