Fontebasso F, painting, Jacob wrestling with the angel (18th cent.). Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.

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. Reconstruction of the prehistoric fish Pandericthys Author Tyler Rhodes; original in the wikipedia.org collection (license CC BY-SA 3.0, no changes). The shape of the skeleton of the pectoral fin and shoulder girdle suggests that Panderichthys rhombolepis "walked" (2006AhlbergPE_ClackJA). At the very least...

Homo ergaster

HOMO ERGASTER The Homo ergaster species lived in Africa 1.8 million years ago and was alive until 600,000 years ago, likely becoming the ancestor of Homo erectus in Asia, Homo neanderthalensis in Europe, and Homo sapiens in Africa (1995CachelS_HarrisJ; 2005KleinR). Homo ergaster is occasionally equated with Homo erectus in publications (2013TattersallI). The most complete Homo ergaster skeleton belongs to an adolescent named "Turkana Boy" (KNM-WT 15000). The young man was between 8 and 12 years old (2010GravesRR_CunninghamDL; 2019BergmanJ). The age of this individual's remains is believed to be 1.6 million years (2007TattersallI). Turkana Boy (reconstruction) Author: Mettmann Neanderthal Museum; source: wikimedia.org collection (license CC BY-SA 4.0, no changes). The pelvis of specimen KNM-WT 15000 is well preserved. It shows ossified acetabulums. In turn, they have spacious acetabular fossae and wide acetabular notches. Based on these elements, it is possible to conc...

Human Children. Retelling of Chapter 10

Short retelling of chapter 10 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 10. THE ARK AND THE CAVE The Book of Genesis does not specify where Noah lived before the flood, but it is plausible his home was in the "land of Nod." To save his family and terrestrial animals, Noah builds an ark measuring "three hundred cubits" long, "fifty cubits" wide, and "thirty cubits" high, coated with pitch inside and out. The vessel has three decks, a pyramidal roof, a side door, and a window, likely at the top. Noah loads his wife, three sons with their wives, and representatives of birds, reptiles, and "clean and unclean cattle." The text lists some "passengers": Noah’s sons, Shem, Ham, and Japheth, and mentions "beasts," "cattle," "creeping things," "flying creatures,"...

1527BenedettiA

Fragment from the book Benedetti A. Anatomice siue historia corporis humani (1527). The author explains the origin of the rare synonym of ligamentum capitis femoris (LCF) – ischion. Quote. Liber V. De femine et eius prolapsu. Cap. XXXI Sinus coxae à graecis cotylae, à nostris acetabula dicuntur, quae hos sinus complent circa quae uersurae siunt, coxendices uocatur, à graecis ischia, à quib ischiadici dicti sunt, qui coxedice laborant. Nam et neruus quo coxendix acetabulo comittitur, ischion quoqʒ dicitur. Translation [Eng] Book V. On the Hip and Its Prolapse. Chapter XXXI. The pelvic sinuses are called cups (cotylae) by the Greeks, and in these sinuses, we have an inkwell (acetabula). The region around which the movements take place is called the coxendices (hip joint), by the Greeks the sciatic (ischia), from which the term ischiadici (related to the hip) comes for those suffering from hip issues. And the sinew/nerve (neruus) which connects the hip (coxendix) to the ...
