The author discusses the anatomy and function of the ligamentum capitis femoris (LCF), and also identifies one of the reasons for its damage.

Australopithecus afarensis

AUSTRALOPITHECUS AFARENSIS In 1735, Carl Linnaeus (1707-1778) placed humans as a species «Homo nosce te ipsum» in the order Anthropomorpha along with monkeys and sloths (1735LinneC). In a publication in 1758, the naturalist transferred humans to the order Primates (1758LinneC). Today, humans and chimpanzees are united in the tribe Hominini, as descended from a common ancestor (2001GrovesCP). It has been established that the chromosome that distinguishes humans from monkeys was formed before 4.5 Ma (2022PoszewieckaB_GambinA). The hominin subfamily Sahelanthropus tchadensis lived in the Republic of Chad (Central Africa) from 7.2±0.31 to 6.8±0.45 Ma (2008LebatardAE_BrunetM; 2012ReynoldsSC_GallagherA). Reconstruction of its musculoskeletal system showed that the creature could have been an upright bipedal primate (2005ZollikoferCP_BrunetM). Fossils of what is probably the first bipedal representative of the hominid family Orrorin tugenensis, lived 6.1-5.7 Ma and still retained adapta...

Human Children. Retelling of Chapter 5

Short retelling of chapter 5 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 5. ADAM AND EVE The Book of Genesis narrates the story of a tribe founded by Adam and Eve, described as the "mother of all living." From a genetic perspective, they are depicted as siblings, with an age difference of 18–25 years. According to the biblical epic, they formed humanity’s first family, sustaining themselves on pre-existing fruits and seeds. Their initial home was the "garden in Eden," located "in the east" relative to the narrator. The text identifies geographic markers for Eden’s location: lands like "Asshur," "Cush," and "Havilah," and rivers named "Pishon," "Gihon," "Hiddekel," and "Phrath." The narrator also notes the region’s economic value, mentioning "gold," ...

Tiktaalik roseae

TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys.

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...
