Homo floresiensis

HOMO FLORESIENSIS Homo floresiensis lived on the island of Flores (Indonesia) 190-50 Kya (2016SutiknaT_RobertsRG). The ancestor of this species is «suspected» to be the Asian subtype Homo erectus, which arrived from the mainland about 800 Kya (2009LyrasGA_DeVosJ). The anatomy of Homo floresiensis is less similar to Homo habilis (2008Gordon_WoodB). Homo floresiensis Author: Cicero Moraes et al. (Arc-Team) ; source: wikimedia.org collection (license CC BY 4.0, no changes). Among the discovered remains of a female Homo floresiensis ( humanorigins . si . edu ) there is a relatively well-preserved left pelvic bone (LB1/7). It has a « typically human » acetabulum (2009JungersWL_DjubiantonoT:Fig.3). The acetabulum has a complete fusion of the three bones that form it and is not hypoplastic (2012BrownP:Fig.4). The acetabular fossa is rounded and deep, continuing downwards and forwards as a wide acetabular notch. This area is the site of attachment and func...

Fragments from the book Sandifort E. Descriptio ossium hominis. (1785). The author briefly writes about the attachment of the ligamentum capitis femoris (LCF). Quote p. 104 [Lat] Os ischium… … Qua spectat pelvim (a) os ischion æquabile est, modice cavatum, ab exteriore profunde sinuatum (b). Sinus hic, quem acetabulum vocant, maximus, sere rotundus, est, dividique potest in partes duas, alteram semilunarem quodammodo, cartilagine tectam (c), hinc æquabilem, alteram altius excavatam, asperam (d), glandulæ muciparæ sedem præbentem, & educentem ligamentum teres, quod capiti ossis femoris infigitur (e). … Quote p. 108-109 [Lat] Femoris os … … Caput magnum, globosum, cartilagine lævi incrustatum, oblique positum (b), id est, sursum introrsumque tendens, magnitudine & figura cum acetabulo (i) congruens, intra illud admittitur, illique alligatur per ligamentum teres, quod firmiter adhæret ab altera parte acetabulo, ab altera sinui profundo, inæquabili, qui in dicto capite est (k...

The First Animals

THE FIRST ANIMALS According to molecular clock data, the separation of the Animal Kingdom from the Plant Kingdom occurred 1609±60 Ma (2004HedgesSB_ShoeJL). Molecular estimates indicate that the last common ancestor of multicellular representatives of the fauna (Metazoa) was Neoproterozoic, most likely younger than 800 million years (2015PisaniD_LiuAG). Biomarkers of metazoan living systems identified in sedimentary deposits indicate their presence in the seas since the Cryogenian period (2018ZumbergeJA_SummonsRE), which began around approximately 720 Ma (2023CohenKM_CarN). Multicellular animals were part of early Ediacaran ecosystems and are found below layers dated to 632.5 ± 0.5 Ma (2007Yin_LHuJ). The oldest fossil of a multicellular organism resembling a sponge (Porifera) is about 600 Ma (2015YinZ_TafforeauP). The last Neoproterozoic glaciation (about 582 Ma) coincides with the appearance of complex organisms in the fossil record (2007BowringSA_AllenPA). Ev...

1899ParsonsFG

An excerpt from the article by Parsons FG. The joints of mammals compared with those of man: a course of lectures delivered at the Royal College of Surgeons of England (1899, pp. 301-306). The paper discusses the anatomy and presence of the ligamentum capitis femoris (LCF) in different animals. The author found in an experiment that in kangaroos, the LCF was stretched during hip extension. Below we publish an excerpt from the abstract and a critique of the lecture in the Lancet.

SOME of the chief points which attract attention in the hip joint of man are the three thickened parts of the capsule called the ilio-femoral, ischio-femoral, and pubo-femoral ligaments, as well as the intra-articular ligamentum teres running from the bottom of the ac...

How TeresI Helps Us

Teresi – a small ligament of the hip joint, also known as the round ligament (lat. ligamentum teres). It supports the body and thus reduces the load on the hip joint.

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...
