Viviane Slon is a paleogeneticist at the Max Planck Institute for Evolutionary Anthropology. [1] [2] 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. [3]
Slon completed her doctoral studies at the Max Planck Institute for Evolutionary Anthropology. [4] She won the 2017 Dan David Prize. [5] She worked at the Sackler Faculty of Medicine at Tel Aviv University on the earliest human fossils outside Africa. [6] [7] She studied the Qafzeh 9 Skull, looking at developmental malocclusions. [8]
In 2018 Slon was appointed a postdoctoral researcher working on neanderthals at the Max Planck Institute for Evolutionary Anthropology. [9] She develops techniques to remove hominin DNA from sediments. [10] [11] [12] Her doctoral supervisor Svante Pääbo decoded the Denisovan gene. [13] [14] Slon visited the Denisova Cave during a symposium, where over one thousand bones are excavated a year. [13]
As her first project, Slon reported the DNA from the tooth of the fourth Denisova individual ever found on earth. [15] [16] She also co-led a team that found Denisovan DNA in excavated dirt as an alternative to finding rare hominin bones. [3]
In 2018, Slon and her colleagues published the genome of Denny, a hybrid hominin. [17] DNA was extracted from a hominin bone found in a Middle Pleistocene layer. [13] [18] [19] Using genetic analysis and radiocarbon dating, the hominin was identified as a girl born more than 50,000 years ago to a Neanderthal mother and a Denisovan father. [13] [20] [21] The work was covered in BBC News, National Geographic, EurekAlert!, The Atlantic and Archaeology magazine. [22] [23] [24] [25] [26] [27]
Slon was selected as one of Nature's 10 in 2018. [3]
Svante Pääbo is a Swedish geneticist and Nobel Laureate who specialises in the field of evolutionary genetics. As one of the founders of paleogenetics, he has worked extensively on the Neanderthal genome. In 1997, he became founding director of the Department of Genetics at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Since 1999, he has been an honorary professor at Leipzig University; he currently teaches molecular evolutionary biology at the university. He is also an adjunct professor at Okinawa Institute of Science and Technology, Japan.
Early modern human (EMH), or anatomically modern human (AMH), are terms used to distinguish Homo sapiens that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species. This distinction is useful especially for times and regions where anatomically modern and archaic humans co-existed, for example, in Paleolithic Europe. Among the oldest known remains of Homo sapiens are those found at the Omo-Kibish I archaeological site in south-western Ethiopia, dating to about 233,000 to 196,000 years ago, the Florisbad site in South Africa, dating to about 259,000 years ago, and the Jebel Irhoud site in Morocco, dated about 315,000 years ago.
The Max Planck Institute for Evolutionary Anthropology is a research institute based in Leipzig, Germany, that was founded in 1997. It is part of the Max Planck Society network.
The Neanderthal genome project is an effort of a group of scientists to sequence the Neanderthal genome, founded in July 2006.
The Sidrón Cave is a non-carboniferous limestone karst cave system located in the Piloña municipality of Asturias, northwestern Spain, where Paleolithic rock art and the fossils of more than a dozen Neanderthals were found. Declared a "Partial Natural Reserve" in 1995, the site also serves as a retreat for five species of bats and is the place of discovery of two species of Coleoptera (beetles).
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(di-NEE-sə-və) are an extinct species or subspecies of archaic human that ranged across Asia during the Lower and Middle Paleolithic. 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, Siberian Federal District, Russia. The cave has provided items of great paleoarchaeological and paleontological interest. Bone fragments of the Denisova hominin originate from the cave, including artifacts dated to around 40,000 BP. Remains of a 32,000-year-old prehistoric species of horse has also been found in the cave.
Neanderthals, also known colloquially as Cavemen, are an extinct species or subspecies 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.
Interbreeding between archaic and modern humans occurred during the Middle Paleolithic and early Upper Paleolithic. The interbreeding happened in several independent events that included Neanderthals and Denisovans, as well as several unidentified hominins.
Mezmaiskaya Cave is a prehistoric cave site overlooking the right bank of the Sukhoi Kurdzhips in the southern Russian Republic of Adygea, located in the northwestern foothills of the North Caucasus in the Caucasus Mountains system.
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. loo In shallow time, advancements in the field of molecular paleontology have allowed scientists to pursue evolutionary questions on a genetic level rather than relying on phenotypic variation alone. By applying molecular analytical techniques to DNA in Recent animal remains, one can quantify the level of relatedness between any two organisms for which DNA has been recovered. Using various biotechnological techniques such as DNA isolation, amplification, and sequencing scientists have been able to gain expanded new insights into the divergence and evolutionary history of countless recently extinct organisms. In February 2021, scientists reported, for the first time, the sequencing of DNA from animal remains, a mammoth in this instance, over a million years old, the oldest DNA sequenced to date.
Johannes Krause is a German biochemist with a research focus on historical infectious diseases and human evolution. Since 2010, he has been professor of archaeology and paleogenetics at the University of Tübingen. In 2014, Krause was named a founding co-director of the new Max Planck Institute for the Science of Human History in Jena.
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 Goyet Caves are a series of connected caves located in Wallonia 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, Belgium. 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.
Genetic studies on Neanderthal ancient DNA became possible in the late 1990s. The Neanderthal genome project, established in 2006, presented the first fully sequenced Neanderthal genome in 2013.
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.
