ABSTRACT A long season of excavation took place at Raqefet cave during the summer of 2006. In the first chamber we exposed an area rich with Natufian human burials (Locus 1), a large bedrock basin with a burial and two boulder mortars (Locus 2), an in situ Natufian layer (Locus 3), and two areas with rich cemented sediments (tufa) covering the cave floor (Loci 4, 5). The latter indicate that at the time of occupation the Natufian layers covered the entire floor of the first chamber.

This review details both what is firmly understood (first echelon issues) and what is contentious concerning humanSAMPLE evolution. Most of the coCHAPTERSntention actually concerns the details (second echelon issues) of human evolution rather than the fundamental issues. For example, both anatomical and molecular evidence on living (extant) hominoids (apes and humans) suggests the close relationship of African great apes and humans (hominins). That relationship is demonstrated by the existing hominoid fossil record, including that of early hominins.

  • New Fossils from Jebel Irhoud, Morocco and the Pan-African Origin of Homo Sapiens Jean-Jacques Hublin1,2, Abdelouahed Ben-Ncer3, Shara E
    LETTER doi:10.1038/nature22336 New fossils from Jebel Irhoud, Morocco and the pan-African origin of Homo sapiens Jean-Jacques Hublin1,2, Abdelouahed Ben-Ncer3, Shara E. Bailey4, Sarah E. Freidline1, Simon Neubauer1, Matthew M. Skinner5, Inga Bergmann1, Adeline Le Cabec1, Stefano Benazzi6, Katerina Harvati7 & Philipp Gunz1 Fossil evidence points to an African origin of Homo sapiens from a group called either H. heidelbergensis or H. rhodesiensis. However, a the exact place and time of emergence of H. sapiens remain obscure because the fossil record is scarce and the chronological age of many key specimens remains uncertain. In particular, it is unclear whether the present day ‘modern’ morphology rapidly emerged approximately 200 thousand years ago (ka) among earlier representatives of H. sapiens1 or evolved gradually over the last 400 thousand years2. Here we report newly discovered human fossils from Jebel Irhoud, Morocco, and interpret the affinities of the hominins from this site with other archaic and recent human groups. We identified a mosaic of features including facial, mandibular and dental morphology that aligns the Jebel Irhoud material with early or recent anatomically modern humans and more primitive neurocranial and endocranial morphology. In combination with an age of 315 ± 34 thousand years (as determined by thermoluminescence dating)3, this evidence makes Jebel Irhoud the oldest and richest African Middle Stone Age hominin site that documents early stages of the H. sapiens clade in which key features of modern morphology were established. Furthermore, it shows that the evolutionary processes behind the emergence of H. sapiens involved the whole African continent. In 1960, mining operations in the Jebel Irhoud massif 55 km south- east of Safi, Morocco exposed a Palaeolithic site in the Pleistocene filling of a karstic network.

  • 10. Doctrine of Man Lecture 14 When Did Adam Live?
    § 10. Doctrine of Man Lecture 14 When Did Adam Live? Good morning! Welcome to Defenders! We are coming to you today from the safety of my hermetically sealed home office, and I am glad that you could join us. The last time I argued that the historical Adam and Eve actually existed even though their stories are cloaked in the language of figuralism and mythology. This raises an obvious question. If the biblical Adam was a historical person who actually lived, then the obvious question arises, when did he live? We can turn to modern science in the attempt to answer this question. For scientists are vitally interested in a question which is empirically equivalent to our question, namely, when did human beings first appear on Earth? The historical Adam may then be located around that time. First of all, however, we need to clarify some terminology. A hominid is the class of animals that includes orangutans, chimpanzees, gorillas, and humans. They are all hominids. A hominin is the class that includes only members of the human lineage since its divergence from the last common ancestor with chimpanzees. The class of hominins includes not only modern man, Homo sapiens, but also archaic species of the genus Homo. It includes as well Australopithecines, which were bi-pedal African apes. Ian Tattersall of the American Museum of Natural History points out that early individuals classed as Homo, such as Homo habilis, Homo erectus, Homo rudolfensis, and so on, all have in common remarkably small brains, hardly larger than those of the Australopithecines.

  • Denisovans, Neanderthals Or Sapiens?
    Could There Have Been Human Families... 8(2)/2020 ISSN 2300-7648 (print) / ISSN 2353-5636 (online) Received: March 31, 2020. Accepted: September 2, 2020 DOI: http://dx.doi.org/10.12775/SetF.2020.019 Could There Have Been Human Families Where Parents Came from Different Populations: Denisovans, Neanderthals or Sapiens? MARCIN EDWARD UHLIK Independent Scholar e-mail: [email protected] ORCID: 0000-0001-8518-0255 Abstract. No later than ~500kya the population of Homo sapiens split into three lin- eages of independently evolving human populations: Sapiens, Neanderthals and Den- isovans. After several hundred thousands years, they met several times and interbred with low frequency. Evidence of coupling between them is found in fossil records of Neanderthal – Sapiens offspring (Oase 1) and Neanderthal – Denisovans (Denisova 11) offspring. Moreover, the analysis of ancient and present-day population DNA shows that there were several significant gene flows between populations. Many introgressed sequences from Denisovans and Neanderthals were identified in genomes of currently living populations. All these data, according to biological species definition, may in- dicate that populations of H. sapiens sapiens and two extinct populations H. sapiens neanderthalensis and H. sapiens denisovensis are one species. Ontological transitions from pre-human beings to humans might have happened before the initial splitting of the Homo sapiens population or after the splitting during evolution of H. sapiens sapiens lineage in Africa. If the ensoulment of the first homo occurred in the evolving populations of H. sapiens sapiens, then occasionally mixed couples (Neanderthals – Sa- piens or Denisovans – Sapiens) created relations that functioned as a family, in which children could have matured.
