Career

Oppenheimer trained in medicine at Oxford and London universities, qualifying in 1971. From 1972 he worked as a clinical paediatrician, mainly in Malaysia, Nepal and Papua New Guinea. He carried out and published clinical research in the areas of nutrition, infectious disease (including malaria), and genetics, focussing on the interactions between nutrition, genetics and infection, in particular iron nutrition, thalassaemia and malaria. From 1979 he moved into medical research and teaching, with positions at the Liverpool School of Tropical Medicine, Oxford University, a research centre in Kilifi, Kenya, and the Universiti Sains Malaysia in Penang. [1]

He spent three years undertaking fieldwork in Papua New Guinea, studying the effects of iron supplementation on susceptibility to infection. His fieldwork, published in the late 1980s, identified the role of genetic mutation in malarious areas as a result of natural selection due to its protective effect against malaria, and that different genotypes for alpha-thalassaemia traced different migrations out to the Pacific. Following that work, he concentrated on researching the use of unique genetic mutations as markers of ancient migrations. [1]

From 1990 to 1994 Oppenheimer served as chairman and chief of clinical service in the Department of Paediatrics in the Chinese University of Hong Kong. He worked as senior specialist paediatrician in Brunei from 1994 to 1996. He returned to England in 1997, writing the book Eden in the East: the drowned continent of Southeast Asia, published in 1998. The book synthesised work across a range of disciplines, including oceanography, archaeology, linguistics, social anthropology and human genetics. [1]

He continued to write books and articles, and began a second career as a researcher and popular-science writer on human prehistory. He worked as consultant on two television documentary series, The Real Eve (Discovery Channel) and Out of Eden (Channel 4), and published a second book, Out of Eden: the Peopling of the World (retitled The Real Eve in USA). This was followed in 2006 by The Origins of the British: a genetic detective story, on the post-glacial peopling of Great Britain and Ireland. In 2009 he was consultant on the BBC TV series The Incredible Human Journey . [1]

Books by Oppenheimer

Eden in the East

In his book Eden in the East: The Drowned Continent of Southeast Asia, published in 1998, Oppenheimer argues that the rise in ocean levels that accompanied the waning of the ice age—as much as 500 feet (150 m)—during the period 14,000–7,000 years ago, must be taken into account when trying to understand the flow of genes and culture in Eurasia. Citing evidence from geology, archaeology, genetics, linguistics, and folklore, he hypothesizes that the Southeast Asian subcontinent of Sundaland was home to a rich and original culture that was dispersed when Sundaland was mostly submerged and its population moved westward. According to Oppenheimer, Sundaland's culture may have reached India and Mesopotamia, becoming the root for the innovative cultures that developed in those areas. He also suggests that the Austronesian languages originate from Sundaland and that a Neolithic Revolution may have started there. [2]

The Real Eve (documentary and US book title) / Out of Eden (UK book title)

In 2002, Oppenheimer worked as consultant on a television documentary series, The Real Eve, produced by the American cable TV network the Discovery Channel and directed by Andrew Piddington. The series was known as Where We Came From in the United Kingdom. The "Eve" in the title refers to Mitochondrial Eve, a name used for the most recent common ancestor of all humans in the matrilineal (mother to daughter) line of descent.

Following the series, Oppenheimer published a book on the same theme, originally titled Out of Eden in the UK and republished as The Real Eve in the US. This work, published in 2004, focuses on Oppenheimer's hypothesis: that approximately 85 thousand years ago, a group of modern humans migrated from East Africa across the Red Sea to South Asia in a single major exodus numbering no more than a few hundred individuals. This lone group of wanderers, he suggests, were the ancestors of all the peoples of the earth except sub-Saharan Africans, their descendants having since migrated all over the Eurasian continent, North Africa, the Pacific islands, and the New World, and radiated into a plurality of physical characteristics, languages, ethnicities and cultures as seen today. [3]

Origins of the British

In his 2006 book The Origins of the British (revised in 2007), Oppenheimer argued that neither Anglo-Saxons nor Celts had much impact on the genetics of the inhabitants of the British Isles, and that British ancestry mainly traces back to the Palaeolithic Iberian people, now represented best by Basques, instead. He also argued that the Scandinavian input has been underestimated. He published an introduction to his book in Prospect magazine [4] and answered some of his critics in a further Prospect magazine article in June 2007. [5] Recent archaeogenetics studies have contradicted Oppenheimer's theory, indicating a population replacement in Britain by a migration of Early European Farmers, ultimately from the Aegean, after c. 4,000 BCE, [6] and another population replacement around the middle of the third millennium BCE, when a migration of Bell Beaker groups carrying significant levels of Steppe Ancestry resulted in the replacement of around 90% of the gene pool in Britain.

In human genetics, the Mitochondrial Eve is the matrilineal most recent common ancestor (MRCA) of all living humans. In other words, she is defined as the most recent woman from whom all living humans descend in an unbroken line purely through their mothers and through the mothers of those mothers, back until all lines converge on one woman.

Several species of humans have intermittently occupied Great Britain for almost a million years. The earliest evidence of human occupation around 900,000 years ago is at Happisburgh on the Norfolk coast, with stone tools and footprints probably made by Homo antecessor. The oldest human fossils, around 500,000 years old, are of Homo heidelbergensis at Boxgrove in Sussex. Until this time Britain had been permanently connected to the Continent by a chalk ridge between South East England and northern France called the Weald-Artois Anticline, but during the Anglian Glaciation around 425,000 years ago a megaflood broke through the ridge, and Britain became an island when sea levels rose during the following Hoxnian interglacial.

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 archaelogical excavations near Siversky Donets 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.

Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project.

The origin of the Basques and the Basque language is a controversial topic that has given rise to numerous hypotheses. Modern Basque, a descendant or close relative of Aquitanian and Proto-Basque, is the only Pre-Indo-European language that is extant in western Europe. The Basques have therefore long been supposed to be a remnant of a pre-Indo-European population of Europe.

The genetic history of the British Isles is the subject of research within the larger field of human population genetics. It has developed in parallel with DNA testing technologies capable of identifying genetic similarities and differences between both modern and ancient populations. The conclusions of population genetics regarding the British Isles in turn draw upon and contribute to the larger field of understanding the history of the human occupation of the area, complementing work in linguistics, archaeology, history and genealogy.

There have been several models of early human migration to the Philippines. Since H. Otley Beyer first proposed his wave migration theory, numerous scholars have approached the question of how, when and why humans first came to the Philippines. The current scientific consensus favors the "Out of Taiwan" model, which broadly match linguistic, genetic, archaeological, and cultural evidence.

<span class="mw-page-title-main">Genetic history of the Iberian Peninsula</span> Ancestry of Spanish and Portuguese people

The ancestry of modern Iberians is consistent with the geographical situation of the Iberian Peninsula in the south-west corner of Europe. As is the case for most of the rest of Southern Europe, the principal ancestral origin of modern Iberians are Early European Farmers who arrived during the Neolithic. The large predominance of Y-Chromosome Haplogroup R1b, common throughout Western Europe, is testimony to a considerable input from various waves of Western Steppe Herders from the Pontic-Caspian Steppe during the Bronze Age.

Various genetic studies on Filipinos have been performed, to analyze the population genetics of the various ethnic groups in the Philippines.

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.
