Homo antecessor. Hip disarticulation

HOMO ANTECESSOR. Hip disarticulation

Postmortem separation of the leg from the pelvis in individuals of own species was performed by our evolutionary predecessors. In particular, this was done in the Homo antecessor community, which practiced cannibalism (2003TuttC). Ferna Y. et al. (1999) described evidence of intentional crushing of the femur diaphysis in a young individual (ATD6-76), presumably to extract bone marrow. The bone retained traces of not only several impacts by a striker, but also of an anvil on which the bone lay. The age of the said find in the Gran Dolina cave (Spain) is estimated at about 780 thousand years (1999FernaY_RosellJ).

The above features indicate that the femur was initially separated from the soft tissues. In the second stage, the butcher had to use a stone tool to cut the muscles and strong external ligaments of the hip joint. In the next stage, he tore, or perhaps cut off, the ligamentum capitis femoris (LCF) to mobilize the hip and further manipulate it.

Homo antecessor colonized the Iberian Peninsula 1200-800 Kya (2015MorenoD_ArsuagaJL). Therefore, the skill of hip arthrotomy in hominids could have appeared more than 780 Kya (2001CarreteroJ_ArsuagaJL). It must be assumed that from this period human ancestors learned about the presence of LCF in their hip joint. Hominids observed LCF in animals when cutting up carcasses. The cutting was done with stone hand axes and blades. The oldest stone tools, 3.3 million years old, were discovered in Kenya (2015HarmandS_RocheH). Stone tools from Kenya with signs of wear, implying the processing of plant and animal tissues by hominins, are dated to the interval of 3.03-2.58 Ma (2023PlummerTW_PottsR).

Thus, knowledge of LCF in animals is more than three million years old. This information is contemporary with the genus Homo itself, which formed between 4.30 and 2.56 Ma (2021PüschelHP_PüschelTA).

«Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ). The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions.

Human Children. Retelling of Chapter 8

Short retelling of chapter 1 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 8. THE LAND OF NOD Cain’s family settled in the land of "Nod," where they established a "city." We propose this tribal group followed a route later known as the Great Khorasan Road, leading Cain, son of Adam, to the Kermanshah Valley in the central Zagros Mountains. There, we believe he founded the settlement of "Enoch," its remnants linked to the archaeological site of Sheikh-e Abad (34°36'42"N, 47°16'11"E). In this village, the newcomers mastered musical instruments, developed metalworking techniques, and some adopted nomadic herding, living in "tents with flocks." As a farmer, Cain likely preserved knowledge of agriculture. Favorable conditions, division of labor, and acquired skills probably fueled population growth among thes...
