Joachim Burger (born 27 June 1969 in Aschaffenburg, West Germany) is a German anthropologist and population geneticist based at Johannes Gutenberg University, Mainz, Germany, where he runs the Palaeogenetics Group at the Institute of Organismic and Molecular Evolution (iOME).
Burger has pioneered the application of ancient DNA technology to resolve anthropological and archaeological questions, particularly concerning humans and domestic animals in the Holocene period. He received his MA in anthropology in 1997, and his PhD in biology at the Georg-August-University, Göttingen, Germany, in 2000. He was made professor (junior professor) in molecular archaeology in 2005, and professor in anthropology in 2010. He is based at Johannes Gutenberg University in Mainz, Germany.
The main focus of Burger's research is human population genetics of Europe in the early Holocene, and of Central Asia during Bronze and Iron Age. [1] He applies palaepopulation-genetic methods, i.e. uses ancient DNA data from archaeological skeletons and statistical inference methods to compare these "fossil" DNA sequences amongst each other and to modern-day populations. He pioneered the field of human palaeo-population genetics. [2] [3] [4] Together with an international team he showed in 2009 that the first European farmers were immigrants to the continent and not descendants of local hunter-gatherers. [5] In 2016, he published the first ancient genome from the Fertile Crescent. [6] The study demonstrates that the first Neolithic farmers had populated Europe from the western/central part of Anatolia [7] [8] but not from Iran. [9] He also works on the population genetics of the Medieval period [10] [11] and of animal domestication. [12]
Burger also is the editor of the journal, Archaeological and Anthropological Sciences and corresponding member of the German Archaeological Institute (DAI).

The Proto-Indo-Europeans are a hypothetical prehistoric population of Eurasia who spoke Proto-Indo-European (PIE), the ancestor of the Indo-European languages according to linguistic reconstruction.
The Natufian culture is a Late Epipaleolithic archaeological culture of the Neolithic prehistoric Levant in Western Asia, dating to around 15,000 to 11,500 years ago. The culture was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture. The Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. The world's oldest known evidence of the production of bread-like foodstuff has been found at Shubayqa 1, a 14,400-year-old site in Jordan's northeastern desert, 4,000 years before the emergence of agriculture in Southwest Asia In addition, the oldest known evidence of possible beer-brewing, dating to approximately 13,000 BP, was found in Raqefet Cave on Mount Carmel, although the beer-related residues may simply be a result of a spontaneous fermentation.
The European Neolithic is the period when Neolithic technology was present in Europe, roughly between 7000 BC and c. 2000–1700 BC. The Neolithic overlaps the Mesolithic and Bronze Age periods in Europe as cultural changes moved from the southeast to northwest at about 1 km/year – this is called the Neolithic Expansion.
The Yamnaya culture or the Yamna culture, also known as the Pit Grave culture or Ochre Grave culture, was a late Copper Age to early Bronze Age archaeological culture of the region between the Southern Bug, Dniester, and Ural rivers, dating to 3300–2600 BCE. It was discovered by Vasily Gorodtsov following his archaeological excavations near the Donets River in 1901-1903. Its name derives from its characteristic burial tradition: Я́мная is a Russian adjective that means 'related to pits ', as these people used to bury their dead in tumuli (kurgans) containing simple pit chambers.
Lactase persistence is the continued activity of the lactase enzyme in adulthood, allowing the digestion of lactose in milk. In most mammals, the activity of the enzyme is dramatically reduced after weaning. In some human populations, though, lactase persistence has recently evolved as an adaptation to the consumption of nonhuman milk and dairy products beyond infancy. Lactase persistence is very high among northern Europeans, especially Irish people. Worldwide, most people are lactase non-persistent, and are affected by varying degrees of lactose intolerance as adults. However, lactase persistence and lactose intolerance do not always overlap.
Ancient DNA (aDNA) is DNA isolated from ancient specimens. Due to degradation processes ancient DNA is more degraded in comparison with contemporary genetic material. Even under the best preservation conditions, there is an upper boundary of 0.4–1.5 million years for a sample to contain sufficient DNA for sequencing technologies. The oldest sample ever sequenced is estimated to be 1.65 million years old. Genetic material has been recovered from paleo/archaeological and historical skeletal material, mummified tissues, archival collections of non-frozen medical specimens, preserved plant remains, ice and from permafrost cores, marine and lake sediments and excavation dirt. On 7 December 2022, The New York Times reported that two-million year old genetic material was found in Greenland, and is currently considered the oldest DNA discovered so far.
Haplogroup K, formerly Haplogroup UK, is a human mitochondrial DNA (mtDNA) haplogroup. It is defined by the HVR1 mutations 16224C and 16311C. It is now known that K is a subclade of U8.
Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia. The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small areas of East Africa, West Asia and Europe. It is especially common among the El Molo and Rendille peoples of Kenya, various regions of Iran, the Lemko people of Slovakia, Poland and Ukraine, the island of Krk in Croatia, the department of Finistère in France and some parts of Scotland and Ireland.
Haplogroup H (Y-DNA), also known as H-L901/M2939 is a Y-chromosome haplogroup.
The genetic history of Europe includes information around the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe.
Haplogroup N1a is a human mitochondrial DNA (mtDNA) haplogroup.
Mark G. Thomas is a human evolutionary geneticist, Professor of Evolutionary Genetics at the Research Department of Genetics, Evolution and Environment at University College London since 2009. Prior to this, he was Cancer Research Campaign Postdoctoral Research Fellow at King's College London and then Wellcome Trust postdoctoral researcher in the department of Biological Anthropology at the University of Cambridge. He has acted as Editor-in-chief of the journal Annals of Human Genetics from 2015 to 2019 and Oct 2020 to Jan 2021.
African admixture in Europe refers to the presence of human genotypes attributable to periods of human population dispersals out of Africa in the genetic history of Europe. For example, certain Y-DNA and mtDNA lineages are thought to have spread from Northeastern Africa to the Near East during the later Pleistocene, and from there to Europe with the Neolithic Revolution.
The Wezmeh Cave is an archaeological site near Islamabad Gharb, western Iran, around 470 km (290 mi) southwest of the capital Tehran. The site was discovered in 1999 and excavated in 2001 by a team of Iranian archaeologists under the leadership of Dr. Kamyar Abdi. Wezmeh cave was re-excavated by a team under direction of Fereidoun Biglari in 2019.
The genetic history of Italy is greatly influenced by geography and history. The ancestors of Italians are mostly Indo-European speakers and pre-Indo-European speakers. During the Roman empire, the city of Rome also attracted people from various regions throughout the Mediterranean basin, including Southern Europe, North Africa and the Middle East. Based on DNA analysis, there is evidence of ancient regional genetic substructure and continuity within modern Italy dating to the pre-Roman and Roman periods.
Theopetra Cave is a limestone cave located in Theopetra village of Meteora municipality, Thessaly, Greece. It is situated on the northeast side of a limestone rock formation that is 3 km (2 mi) south of Kalambaka. The site has become increasingly important as human presence is attributed to all periods of the Middle and Upper Paleolithic, the Mesolithic, Neolithic and beyond, bridging the Pleistocene with the Holocene.
Early European Farmers (EEF), First European Farmers (FEF), Neolithic European Farmers, Ancient Aegean Farmers, or Anatolian Neolithic Farmers (ANF) are names used to describe a distinct group of early Neolithic farmers who brought agriculture to Europe. Although the spread of agriculture from the Middle East to Europe has long been recognised through archaeology, it is only recent advances in archaeogenetics that have confirmed that this spread was strongly correlated with a migration of these farmers, and was not just a cultural exchange.
In archaeogenetics, the term Western Hunter-Gatherer (WHG), West European Hunter-Gatherer, Western European Hunter-Gatherer, Villabruna cluster, or Oberkassel cluster names a distinct ancestral component of modern Europeans, representing descent from a population of Mesolithic hunter-gatherers who scattered over Western, Southern and Central Europe, from the British Isles in the west to the Carpathians in the east, following the retreat of the ice sheet of the Last Glacial Maximum.
In archaeogenetics, the term Eastern Hunter-Gatherer (EHG), sometimes East European Hunter-Gatherer, or Eastern European Hunter-Gatherer is the name given to a distinct ancestral component that represents descent from Mesolithic hunter-gatherers of Eastern Europe.
In archaeogenetics, the term Western Steppe Herders (WSH), or Western Steppe Pastoralists, is the name given to a distinct ancestral component first identified in individuals from the Eneolithic steppe around the turn of the 5th millennium BC, subsequently detected in several genetically similar or directly related ancient populations including the Khvalynsk, Sredny Stog, and Yamnaya cultures, and found in substantial levels in contemporary European, West Asian and South Asian populations. This ancestry is often referred to as Yamnaya ancestry, Yamnaya-related ancestry, Steppe ancestry or Steppe-related ancestry.
