Katerina Douka (born c. 1980) is an archaeological scientist whose work focuses on the spatio-temporal pattern of human dispersals and extinctions across Eurasia,including Neanderthals,Denisovans and modern Homo sapiens .
Douka completed a B.Sc. in archaeological conservation at the Technological University of Athens,Greece in 2004,followed by an M.Sc. in archaeological science at the University of Oxford,U.K. Her Masters dissertation was titled Seasonality of Neanderthal Occupation at Vanguard Cave,Gibraltar. She studied for her PhD at Oxford 2006–2011. Her doctoral research involved developing of a new protocol for screening and dating carbonates using radiocarbon,the CarDS or carbon density separation method. She used this new methodology to date early shell beads from Upper Palaeolithic sites across Eurasia. [2] This work provided a new chronology for the early arrival of modern humans in the Middle East. [3]
Following her Phd,Douka held a Junior Research Fellowship at Linacre College,University of Oxford,and a William Golding Junior Research Fellowship at Brasenose College,University of Oxford 2014–2018. During her Linacre fellowship she worked as a Postdoctoral Researcher on the “AHOB3”(Ancient Human Occupation of Britain 3) project funded by the Leverhulme Trust. [4] During her Brasenose fellowship she worked as a Postdoctoral Researcher on an ERC funded project “PalaeoChron”(Precision Dating of the Palaeolithic of Eurasia) led by Professor Tom Higham,based at the RLAHA,School of Archaeology. In 2017,she joined the Max Planck Institute for the Science of Human History,Department of Archaeology,Jena,Germany,where she is Principal Investigator / Group Leader on the “FINDER”(Fossil Fingerprinting and Identification of new Denisovan remains in Pleistocene Asia) project funded by the European Research Council. [5] She has pioneered the application of the ZooMS technique (Zooarchaeology by mass spectrometry) to ancient human fossils,enabling the identification of small fragments of bone on the basis of collagen proteins. [6] Her research has provided important insights into early human migrations,the chronology of Neanderthal extinction in Europe,and the nature and chronology of the Denisovians,another distinct branch of human evolution. [7] [8] Her research on early human origins was featured as a research highlight by the European Research Council in 2018,with fellow grantees Tom Higham and Svante Pääbo. [9] She is currently an assistant editor for the journal PNAS.
The Mousterian is an archaeological industry of stone tools,associated primarily with the Neanderthals in Europe,and to the earliest anatomically modern humans in North Africa and West Asia. The Mousterian largely defines the latter part of the Middle Paleolithic,the middle of the West Eurasian Old Stone Age. It lasted roughly from 160,000 to 40,000 BP. If its predecessor,known as Levallois or Levallois-Mousterian,is included,the range is extended to as early as c. 300,000–200,000 BP. The main following period is the Aurignacian of Homo sapiens.
Archaic humans is a broad category denoting all species of the genus Homo that are not Homo sapiens. Among the earliest modern human remains are those from Jebel Irhoud in Morocco,Florisbad in South Africa (259 ka),,Omo-Kibish I in southern Ethiopia .,and Apidima Cave in Southern Greece. Some examples of archaic humans include H. antecessor (1200–770 ka),H. bodoensis (1200–300 ka),H. heidelbergensis (600–200 ka),Neanderthals,H. rhodesiensis (300–125 ka) and Denisovans.
Ksar Akil is an archeological site 10 km (6.2 mi) northeast of Beirut in Lebanon. It is located about 800 m (2,600 ft) west of Antelias spring on the north bank of the northern tributary of the Wadi Antelias. It is a large rock shelter below a steep limestone cliff.
Vindija Cave is an archaeological site associated with Neanderthals and modern humans,located in the municipality of Donja Voća,northern Croatia. Remains of three Neanderthals were selected as the primary sources for the first draft sequence of the Neanderthal genome project in 2010. Additional research was done on the samples and published in 2017.
The Denisovans or Denisova hominins(də-NEE-sə-və) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic,and lived,based on current evidence,from 285 to 25 thousand years ago. Denisovans are known from few physical remains;consequently,most of what is known about them comes from DNA evidence. No formal species name has been established pending more complete fossil material.
Denisova Cave is a cave in the Bashelaksky Range of the Altai Mountains in Siberia,Russia.
Neanderthals are an extinct group of archaic humans who lived in Eurasia until about 40,000 years ago. The type specimen,Neanderthal 1,was found in 1856 in the Neander Valley in present-day Germany.
Molecular paleontology refers to the recovery and analysis of DNA,proteins,carbohydrates,or lipids,and their diagenetic products from ancient human,animal,and plant remains. The field of molecular paleontology has yielded important insights into evolutionary events,species' diasporas,the discovery and characterization of extinct species.
Ust'-Ishim man is the term given to the 45,000-year-old remains of one of the early modern humans to inhabit western Siberia. The fossil is notable in that it had intact DNA which permitted the complete sequencing of its genome,one of the oldest modern human genomes to be so decoded.
The Obi-Rakhmat Grotto is a Middle Paleolithic prehistoric site that yielded Neanderthal fossils. It is a shallow karst cave near the junction of the Chatkal and Pskem Rivers at the southwestern end of the Talassky Alatau Range in the Tien Shan Mountains,100 km (62 mi) northeast of Tashkent,Uzbekistan.
Southwest Asian Neanderthals were Neanderthals who lived in Turkey,Lebanon,Syria,Israel,Palestine,Iraq,and Iran - the southernmost expanse of the known Neanderthal range. Although their arrival in Asia is not well-dated,early Neanderthals occupied the region apparently until about 100,000 years ago. At this time,Homo sapiens migration seem to have replaced them in one of the first anatomically-modern expansions out of Africa. In their turn,starting around 80,000 years ago,Neanderthals seem to have returned and replaced Homo sapiens in Southwest Asia. They inhabited the region until about 55,000 years ago.
Okladnikov Cave is a paleoanthropological site located in the foothills of the Altai Mountains in Soloneshensky District,Altai Krai in southern Siberia,Russia. The cave faces south and is located on a Devonian karst escarpment,lying about 14 metres (46 ft) above the left bank of the Sibiryachikha River valley below;the river itself is a tributary of the Anuy River.
The Goyet Caves are a series of connected caves located in Belgium in a limestone cliff about 15 m (50 ft) above the river Samson near the village of Mozet in the Gesves municipality of the Namur province. The site is a significant locality of regional Neanderthal and European early modern human occupation,as thousands of fossils and artifacts were discovered that are all attributed to a long and contiguous stratigraphic sequence from 120,000 years ago,the Middle Paleolithic to less than 5,000 years ago,the late Neolithic. A robust sequence of sediments was identified during extensive excavations by geologist Edouard Dupont,who undertook the first probings as early as 1867. The site was added to the Belgian National Heritage register in 1976.
Thomas F. G. Higham is an archaeological scientist and radiocarbon dating specialist. He has worked as Professor of Archaeological Science at the University of Oxford,UK,where he was the Director of the Oxford Radiocarbon Accelerator Unit (ORAU) in the Research Lab for Archaeology and the History of Art. He is best known for his work in dating the Neanderthal extinction and the arrival of modern humans in Europe. He is Professor in the Department of Evolutionary Anthropology at the University of Vienna.
Denny is an ~90,000 year old fossil specimen belonging to a ~13-year-old Neanderthal-Denisovan hybrid girl. To date,she is the only first-generation hybrid hominin ever discovered. Denny’s remains consist of a single fossilized fragment of a long bone discovered among over 2,000 visually unidentifiable fragments excavated at the Denisova Cave in the Altai Mountains,Russia in 2012.
Viviane Slon is a paleogeneticist at the Max Planck Institute for Evolutionary Anthropology. She identified that a teenage girl born 90,000 years ago had both Neanderthal and Denisovan parents. She was selected as one of Nature's 10 in 2018.
The Uluzzian Culture is a transitional archaeological culture between the Middle Paleolithic and the Upper Paleolithic,found in Italy and Greece.
Zenobia Jacobs is a South African-born archaeologist and earth scientist specialising in geochronology. She is a professor at the University of Wollongong,Australia.
The 2022 Nobel Prize in Physiology or Medicine was awarded to the Swedish geneticist Svante Pääbo "for his research in the field of genomes of extinct hominins and human evolution". It was announced by Thomas Perlmann,secretary of the Nobel Assembly at Karolinska Institutet in Stockholm,Sweden,on 3 October 2022.
