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 ).

50 TABLES OF EVIDENCE

  Ancient Egypt is the birthplace of the Book of Genesis Arkhipov S.V. 50 Tables of Evidence for the Composition of Genesis in Late Second Intermediate Period Egypt: The Protograph Before the Oral Tradition. Joensuu : Author's Edition, 2026. GGKEY: ZPYTRNR69CB  https://play.google.com/store/books/details?id=Dw7PEQAAQBAJ http://books.google.com/books/about?id=Dw7PEQAAQBAJ ASIN: B0GXWTLSLK https://www.amazon.com/dp/B0GXWTLSLK Synopsis This monograph presents a fundamental revision of the dating and origin of the Book of Genesis , challenging the dominant hypothesis, which dates the text to the mid-first millennium BCE. Through a systematic analysis presented in 50 comparative tables, the author argues that the protograph of Genesis was a deliberate literary compilation created in Egypt during the late Second Intermediate Period (ca. 17th–16th centuries BCE), shortly after the Minoan eruption. The core of the research concerns the non-oral origin of the text. By ident...

Grok. Review of the Article by S.V. Arkhipov "Why Restoration of the Acetabular Labrum May Be Ineffective?".

  At our request, Grok, artificial intelligence developed by xAI, wrote a review of the article by Arkhipov SV. Why Acetabular Labrum Repair May Be Ineffective: A Note on the Mysterious ‘Dark Matter’ in the Hip Joint ([Ru]  Архипов СВ . Почему восстановление вертлужной губы может быть неэффективно?: Заметка о таинственной «темной материи» в тазобедренном суставе. 06.04.2025 ). In accordance with the comments, the article was revised and sent for re-review to the ChatGPT language model prepared to assist in the analysis and editing of texts (OpenAI, 2025).  Below is the original text of the review by Grok: Review of the Article by S.V. Arkhipov "Why Restoration of the Acetabular Labrum May Be Ineffective?: A Note on the Mysterious 'Dark Matter' of the Hip Joint". This review focuses on the analysis of argumentation, as requested. The author asserts that restoration of the acetabular labrum fails to prevent hip joint instability and osteoarthritis when the ligame...
