Spencer Wells [1] (born April 6, 1969) is an American geneticist, anthropologist, author and entrepreneur. He co-hosts The Insight podcast with Razib Khan. Wells led The Genographic Project from 2005 to 2015, as an Explorer-in-Residence at the National Geographic Society, and is the founder and executive director of personal genomics nonprofit The Insitome Institute.
Wells was born in Marietta, Georgia and grew up in Lubbock, Texas. [2] He attended both All Saints School and Lubbock High School, and received a National Merit Scholarship. He obtained a Bachelor of Science in biology from the University of Texas at Austin in 1988 and a Ph.D. in biology from Harvard University in 1994. He was a postdoctoral fellow at Stanford University between 1994 and 1998, and a research fellow at the University of Oxford from 1999 to 2000.
Wells did his Ph.D. work under Richard Lewontin, and later did postdoctoral research with Luigi Luca Cavalli-Sforza and Sir Walter Bodmer. His work, which has helped to establish the critical role played by Central Asia in the peopling of the world, has been published in journals such as Science , American Journal of Human Genetics , and the Proceedings of the National Academy of Sciences .
Wells is renowned[ according to whom? ] for his logistically complex sample-collecting expeditions in remote parts of the world. EurAsia98, which in 1998 took him and his team from London to the Altai Mountains on the Mongolian border, via an overland route through the Caucasus, Iran and the -stans of Central Asia, was sponsored by Land Rover. In 2005 he led a team of Genographic scientists on the first modern expedition to the Tibesti Mountains in northern Chad, and in 2006 he led a team to the Wakhan Corridor on the Tajik-Afghan border. His work has taken him to more than 100 countries.
He wrote the book The Journey of Man: A Genetic Odyssey (2002), [3] which explains how genetic data has been used to trace human migrations over the past 50,000 years, when modern humans first migrated outside of Africa. According to Wells, one group took a southern route and populated southern India and southeast Asia, then Australia. The other group, accounting for 90% of the world's non-African population (some 5.4 billion people as of 2014), took a northern route, eventually peopling most of Eurasia (largely displacing the aboriginals in southern India, Sri Lanka and Southeast Asia in the process), North Africa and the Americas. Wells also wrote and presented the 2003 PBS/National Geographic documentary of the same name. Wells has contributed to efforts to determine the date of Y-chromosomal Adam. [4]
From 2005-2015, Wells led the Genographic Project, undertaken by the National Geographic Society, IBM, and the Waitt Foundation, [5] which aimed to create a picture of how our ancestors populated the planet by analyzing DNA samples from around the world. [6] The project is credited with creating the personal genomics industry.
He has presented the results of his work around the world, including at the 2007 TED conference, where he spoke specifically about human diversity. [7] Wells was a keynote speaker at the Science & Technology Summit in The Hague on November 18, 2010. He also gave the keynote address at the University of Texas College of Natural Sciences commencement exercises on May 21, 2011.
Wells was one of the keynote speakers at the Southern California Genealogical Society Jamboree that was co-sponsored by the International Society of Genetic Genealogy on June 3, 2013. The focus was on Family History and DNA: Genetic Genealogy in 2013, where he was quoted as saying:
Since 2005, the Genographic Project has used the latest genetic technology to expand our knowledge of the human story, and its pioneering use of DNA testing to engage and involve the public in the research effort has helped to create a new breed of "citizen scientist." Geno 2.0 expands the scope for citizen science, harnessing the power of the crowd to discover new details of human population history. [8]
In July 2020, Wells attracted criticism [9] for tweeting that Israel should be bombed “until the sand turns to glass”. [10] Wells was involved in a heated discussion on Twitter, set against a planned Israeli annexation of additional territory in the West Bank. [11] [12] Some of his comments attracted criticism [13] from the online edition of Algemeiner Journal . [14]
The University of Texas at Austin subsequently distanced itself from Wells, stating, "Spencer Wells is no longer a faculty or advisory council member at UT. He previously had a courtesy, unpaid appointment as a part-time adjunct that did not involve teaching. That ended in May and was not renewed. We do not have any association with the views held by Mr. Wells." [14] [15]
National Geographic subsequently removed all of Wells' content from its site, citing a violation of its journalistic ethics policy. [16]
Wells is married to Holly Morse, [17] and the two have lived in Lombok, Indonesia since 2020. He was previously married to Trendell Thompson (1998-2005), with whom he has two children, Sasha Thompson-Wells and Margot Thompson-Wells; and Pamela Caragol Wells (2005-2015).

Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output. In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup. Genetic testing can also be used to determine biological relatives, such as a child's biological parentage through DNA paternity testing, or be used to broadly predict an individual's ancestry. Genetic testing of plants and animals can be used for similar reasons as in humans, to gain information used for selective breeding, or for efforts to boost genetic diversity in endangered populations.
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 Human Genome Diversity Project (HGDP) was started by Stanford University's Morrison Institute in 1990s along with collaboration of scientists around the world. It is the result of many years of work by Luigi Cavalli-Sforza, one of the most cited scientists in the world, who has published extensively in the use of genetics to understand human migration and evolution. The HGDP data sets have often been cited in papers on such topics as population genetics, anthropology, and heritable disease research.
Paleo-Indians or Paleo-Americans were the first peoples who entered and subsequently inhabited the Americas during the final glacial episodes of the late Pleistocene period. The prefix paleo- comes from the Ancient Greek adjective: παλαιός, romanized: palaiós, lit. 'old; ancient'. The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic.
The Genographic Project, launched on 13 April 2005 by the National Geographic Society and IBM, was a genetic anthropological study that aimed to map historical human migrations patterns by collecting and analyzing DNA samples. The final phase of the project was Geno 2.0 Next Generation. Upon retirement of the site, 1,006,542 participants in over 140 countries had joined the project.
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 K or K-M9 is a genetic lineage within human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9, and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent except Antarctica.
Haplogroup L-M20 is a human Y-DNA haplogroup, which is defined by SNPs M11, M20, M61 and M185. As a secondary descendant of haplogroup K and a primary branch of haplogroup LT, haplogroup L currently has the alternative phylogenetic name of K1a, and is a sibling of haplogroup T.
The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003.
