Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

On the Role of the Ligamentum Capitis Femoris in the Maintenance of Different Types of Erect Posture S.V. Arkhipov Keywords: ligamentum capitis femoris, ligamentum teres, ligament of head of femur, abductor muscle group, role, function, hip joint, model, biomechanics, walk, gait cycle, single-legged stance ABSTRACT New experimental and clinical data on the function of the ligamentum capitis femoris (LCF) and its participation in maintaining an erect posture were obtained. It was established that this anatomical element is involved in constraining the hip joint adduction and may ﬁ x the joint in the frontal plane, turning it into an analogue of a second-class lever. In both unstrained one-support and asymmetrical two-support orthostatic postures, when the LCF is stretched and the abductor muscle group is exerted, a load equal to the body weight is evenly distributed between the upper and lower hemispheres of the caput femoris. In addition, the LCF fu...

Human Children. Retelling of Chapter 6

Short retelling of chapter 6 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 6. THE GARDEN OF EDEN According to the Book of Genesis, humanity’s earliest ancestors emerged "in the garden of Eden." The text specifies that this idyllic garden was located "in Eden, toward the east." A nameless river flowed from Eden, irrigating the garden, suggesting that "Eden" encompasses a broader region, while the "garden in Eden" is a distinct, cultivated space. Genesis portrays the garden as a divine plantation, established by "Lord God," with humans tasked to tend and maintain it. The garden teemed with diverse trees, including fruit-bearing ones, and later hosted birds, wild animals, and domesticated livestock. Alongside humans, it harbored supernatural beings like cherubim (kyruvy), a serpent, and other divine entities. A s...

2025ArkhipovSV. Why Acetabular Labrum Repair May Be Ineffective

Original in Russian is available at the link: С.В. Архипова «Почему восстановление вертлужной губы может быть неэффективно?» (06.04.2025) , below is a machine translation edited by a non-native speaker (version dated 06/04/2025). Thematic Internet Journal About round ligament of femur April 2025 WHY ACETABULAR LABRUM REPAIR MAY BE INEFFECTIVE?: A NOTE ON THE MYSTERIOUS "DARK MATTER" OF THE HIP JOINT S.V. Arkhipov, Independent Researcher, Joensuu, Finland Abstract Acetabular labrum repair and reconstruction do not prevent hip joint instability during gait and the development of osteoarthritis in the case of an elongated ligamentum capitis femoris. This conclusion is based on mathematical calculations and analysis of experiments conducted on a mechanical hip joint model.
