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...

THE ROLE OF THE HIP JOINT LIGAMENTS

  The role of the hip joint ligaments Ligaments tighten when the pelvis tilts, support the body, and correct the movement of the center of mass. A horizontal position of the pelvis in a single-leg stance and during walking is pathological.

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...
