Use data from a previous ancestry test to get even more accurate results through GPS Origins!

Already have a high-resolution autosomal DNA test? No need to swab and submit DNA again.The GPS Origins algorithm accepts the raw data DNA test results from Ancestry.com, FamilyTreeDNA, 23andMe, and National Geographic.

GPS Origins™ is a revolutionary DNA test  for ancestry that takes you deep into your family history. Traditionally, a DNA test for ancestry provides a report of your “ethnicity” and locate parts of your DNA in broad continental sweeps, but nothing specific, not even to the country level. 

This test combines the latest genetic research with a new ancestral tracking technique to pinpoint more precisely where your DNA began. 

This advanced autosomal ancestry test is so specific, it may even indicate the town or village where groups of your ancestors from different cultures met—building a vibrant picture of the migration journeys that formed your deep genealogical heritage.

·        New ancestral tracking technique pinpoints your ancestry 

·        800,000 autosomal genetic markers tested, 862 reference populations analyzed, 36 gene pools analyzed

Pinpoint your DNA using existing data from your previous ancestral test! 

The GPS Originstest is the leading ancestry test in terms of accuracy, analyzing over 800,000 markers, 36 gene pools and 862 reference populations. This test has the ability to trace a person's signature going back 1,000 years or more and provides a level of specificity no other ancestral test can replicate: Results provide pinpoint geographical-local information—sometimes to within a radius of 20 miles—by identifying geographic coordinates, much like a car's GPS system. When you upload your existing autosomal data (see How It Works), you get a fully-personalized report based on our unique analysis of your genetic signature.

Your 3-Part Results Report:

  • Identifies your top three ancestral origins (the gene pools or ancestral communities that contributed significant portions of your genetic makeup) and shows the percentages of DNA you inherited from each. The report is much more detailed than a simple “ethnicity test
  • Contains maps illustrating the two most important migration journeys and describes how your ancestors’ circumstances changed as they crossed continents to find better lives.
  • Provides a summary page of helpful links to discover additional information to reveal your ancestral origins

This DNA heritage test:

  • Identifies when and where your DNA formed by matching the populations that came together to create a genetic line leading to you
  • Traces the migration route of your DNA back to where it originated from and dated the age of your DNA signature. It does this for both your maternal and paternal lineages indicating where your DNA began

Science behind the Test

This test is based on a new way of viewing human populations that considers everyone as mixed from different gene pools. This model is fundamentally different from existing ancestry testing, which suggest humans branched from just three or four populations that changed over time. Instead, the test relies upon genetic uniqueness created by mixing global gene pools in different proportions.

The test utilizes autosomal DNA inherited from chromosomes 1-22, which are more sensitive to the genetic signature of your most recent common ancestors. GPS Origins uses 36 gene pools to trace the origin of your DNA—more than twice the number being used by other methods.


The Test Creator

The algorithm was developed at the University of Sheffield, led by the research team of Dr. Eran Elhaik. Dr. Elhaik was one of the creators of the original technology. Nature Communications published a peer review paper describing the science behind this algorithm April 29th, 2014. The accuracy of the test was demonstrated by identifying the DNA signature of ancient Ashkenazic Jews and their formation approximately 1,500-2,000 years ago.

      Other DNA tests for ancestry provide a limited ethnic composition at a regional or country level. For example, they might indicate 33% East Asian, 40% sub-Saharan African and 27% European.

      GPS Origins goes beyond these broad ethnic classifications to identify your ancestral origins to a precise geographic location using an unprecedented number of gene pools and reference populations.

      This is an Autosomal DNA test, also known as a SNP (pronounced ‘snip’) test. It extracts markers from your Y-Chromosome DNA, X-Chromosome DNA and Mitochondrial DNA.

      There are four types of DNA:

      • Y-DNA, which only occurs on the Y-chromosome, is passed down from father to son through the generations, and is only inherited by males.
      • X-DNA, which only occurs on the X-chromosome, is inherited by women from both parents, and by men from the mother.
      • Mitochondrial DNA (also known as mitochondria or mtDNA) is passed down through the maternal line, and is inherited by sons and daughters, but only passed on by females. It is the least changeable type of DNA, found outside the cell nucleus, not on a chromosome.
      • Autosomal DNA can be inherited from hundreds of thousands of your ancestors through the ages. Autosomal DNA can be found in 22 chromosomes, and provides 90% of your DNA.

      This test examines nearly 800,000 of your autosomal markers (SNPs) and compares them with the distinctive mutations in the gene pools of 862 reference populations. This pinpoints the places and times where your DNA last changed.

      The accuracy depends on your family history. If your parents are from the same place or two different locations, and not mixed themselves, the test can trace your DNA signature back to the country of origin 90% of the time. The test will predict the correct continent.

      In a study of people from across the world, the GPS Origins’ algorithm predicted continental origins with 98% accuracy, assigned 83% of the individuals to their country of origin, and, where applicable, 66% of them to their regional locations.

      If your ancestors were from Western Europe, and your parents came from the same region, not moving far from the place that they came from, the test will place your DNA signature within 50 miles of its true origin, and often closer.

      Your results will show the origin as a point on a map. Any expected error appears as a circle around the point - the smaller the circle, the more accurate the result. The accuracy also depends on the size of the reference population in a given area; the larger the reference group, the more accurate the results will be.

      The accuracy of GPS Origins correlates to the number of reference populations we use.

      GPS Origins works like a car’s satellite navigation system, using reference points to locate a position. If you add more reference points, the accuracy increases. In the same way, the GPS Origins algorithm will improve accuracy with more reference populations. Please participate in our questionnaire as your information will help us in this process. Your answers to the questionnaire will NOT affect your results.

      It's usually one of two reasons:

      1. The raw data you upload must be in .ZIP format. Please do not try to upload a PDF, Word, or other type of file
      2. This may be the result of an insufficient amount of DNA data for the GPS Origins algorithm to calculate your report. We recommend going back to your original provider of the data and requesting a full data file

      While we accept results from other companies, we recommend using the GPS Origins test because it tests 800,000 markers, one of the largest sets of DNA markers of all commercial DNA tests for ancestry. The GPS Origins DNA test also includes many unique markers that cannot be found in other commercial tests and will be used in our future tests. You will not be able to take these future tests with raw data DNA test results provided by other companies. Additionally, if you upload raw data from another ancestry test, please understand that your Advanced Autosomal results are dependent on the quality of their genotyping. Lower quality genotypes may affect your GPS Origins results.

      GPS Origins test allows you to trace your DNA back around 1,000 years, or more, to the place where your DNA began.

      The test uses 36 global gene pools to calculate the genetic signature of your autosomal DNA. For example: Fennoscandia 19%, Southern France 14%, Orkney Islands 20%, and so on. Next, it compares your unique DNA signature to populations all over the world (who we know have lived in the same location for a substantial period) to locate where your DNA began. In some cases, GPS Origins traces your DNA to the village or town level. Finally, it calculates two genetic lineages by tracing the migration routes of your DNA, using its ancient signature moving back through time.

      The test looks at the genetic composition of your DNA—your DNA signature—and compares it to a database of over 10,000 signatures from 862 populations with known geographic locations to identify the place where it began about 1,000 years ago.

      We have identified 36 gene pools around the world. Each human population is made up of a mixture of these gene pools. In the distant past, individual migrations were rare. Genetic mixing tended to occur when large groups of people moved from one area to another, through invasion or mass migration. As the incoming gene pool mixed with the local one, a new genetic signature was created across the whole population.

      The GPS Origins test assumes that your DNA signature is unique to you but shares many characteristics with the populations or tribes from which it originated. By comparing your DNA to the signature mixes within different populations, GPS Origins can pinpoint the origin of your DNA.

      The algorithm works out the differences, or genetic ‘distance’ between your DNA and the DNA population signatures in our database, and converts them to geographic distances. Then, like a car satellite navigation system, it uses the distances to calculate the coordinates of your DNA origin, which marks the spot where your DNA most recently changed at the population level. It occurs when two different populations came together and created your DNA signature.

      Using a similar method, GPS Origins then works backward to find two more points and plots the journey to where your DNA was mixed. It repeats this calculation for each element of your parental DNA.

      Your report presents mixture proportions from 36 possible gene pools that cover the whole world as well as the history of the primary gene pools. Your report also shows the geographical origins of your DNA, which could be a country or as close to the nearest town. Your DNA signature was created when two different population groups mixed and created a new genetic signature—the one that you ultimately inherited.

      You also see two migration routes for your DNA—one for each side of your family—back to where it came from, which may originate up to 10,000 years ago. Finally, GPS Origins dates the age of your DNA signature corresponding to when it last underwent a substantial change at the population level.

      GPS Origins is a great tool to help you research your family tree!

      A Gene Pool, also referred to as Ancestral Origin, is the collective set of genetic information within a distinct region where populations had limited interactions with populations from outside the group for up to about 20,000 or 60,000 years. So far, 36 human gene pools around the world have been identified with each human population made up of a mixture of several such gene pools. In the distant past, genetic mixing tended to occur when large groups of people moved from one area to another, through invasion or mass migration. The GPS Origins test pinpoints the origin of your DNA by comparing it to the signature mixtures in different populations. Your personalized report shows the percentages of DNA you inherited and provides you with the history of the top three Gene Pools.

      Also referred to as a Study Base, a reference population is a defined, representative sample of individuals during a specific time range used to establish norms for reference ranges. GPS Origins uses 862 reference populations in its database when calculating your results. This large number of reference populations, obtained from publicly referenced datasets, along with the 36 gene pools helps deliver the accuracy in your GPS Origins results.

      A Migration Pattern is the path your DNA traveled over the past 2,000-4,000 years. The GPS Origins test traces your migration route back to where it originated and dates the age of your DNA signature. The test provides this information for both your parental lineages, indicating where your DNA began. Your results are detailed in a report that reveals a vibrant picture of where and how your ancestors lived, and the conditions that led them to migrate. It also contains maps illustrating the two most important migration journeys and describes how your ancestors’ circumstances changed as they crossed continents to find better lives. Note: The GPS Origins test is an Autosomal (SNP) test that is not gender specific. Although both Migration Patterns represent your Maternal and Paternal DNA route, we cannot differentiate which route is specifically your parents’ individual route at this time.

      GPS Origins ancestry test does not report the geographic origins of individual ancestors, but the geographical origin of your DNA. You can be certain that some of your ancestors came from these places within the period indicated.

      Assume that your four grandparents came from East Asia. Although they are four different individuals, their DNA signature is very similar, and the GPS Origins test would count that as one. In other words, when your ancestors stay in the same place and reuse the same genes it does not change the DNA signature; this is considered a single DNA signature and will infer its East Asian geographical origins.

      Discovering your genetic origin will help you answer the question of where you are from beyond the written record of your family history. It can help you open up further avenues of research and you can learn more about the lives of your ancestors at the point in history when your DNA began.

      Your ‘ancestral family’ is much larger than your immediate family and you may be able to find out much more about their lives and culture with GPS Origins.

      Because this ancestry testing provides an accurate location, you can discover more about the place where your distant ancestors originated. This test helps you use historical and archaeological research to find out about the time and conditions in which your distant ancestors lived.

      GPS Origins shows the origin of your DNA and those of users who choose to share it. These results are indicative of tribal DNA membership, but not necessarily direct familial relationships.

      In the case that one of your parents is of mixed origins because your grandparents are from two different places (e.g., England and Greece), GPS Origins migration lines for that parent would be traced along the middle migration paths of your grandparents (e.g., Hungary). This could be revealed via a larger circle (greater radius) around a stopping point, reflecting higher uncertainty in this area. GPS Origins is the story of your DNA, not necessarily of people. Your (and their) DNA may indeed have come from a region that no one remembers existed.

      We are constantly developing improved tools that will give you more accurate and informative questions about your past, so stay tuned.

      GPS Origins reports the results for two lineages (your parents) which may indicate your parental origins that were inherited from your maternal and paternal grandparents, and so on down the maternal and paternal line.

      If your grandparents and parents are of mixed ancestry, the test identifies the most dominant origins, which may differ between siblings because they inherited different genetic material from each parent.

      For example, imagine that your parents have hazel and brown eyes. You and your sibling(s) may have blue, hazel, or brown eyes because each one of you inherited a different trait from each parent.

      So which sibling’s GPS Origins results are the most correct? They all are correct because each tells a story of different ancestral traits from your family. Despite coming from the same parents, the genetic traits of you and your sibling(s) may show the different path your ancestors have chosen. Combining sibling results together would yield your complete family story. The only siblings with the same result would be identical twins because they have identical DNA.

      In the case that one of your parents is of mixed origins because your grandparents are from two different places (e.g., England and Greece), GPS Origins migration lines for that parent may be traced along the middle migration paths of your grandparents (e.g., Hungary). This could be revealed via a larger circle (greater radius) around a stopping point, reflecting higher uncertainty in this area. GPS Origins is the story of your DNA—not necessarily of people. Your (and their) DNA may indeed have come from a region that no one remembers existed.

      We are constantly developing improved tools that will give you more accurate and informative questions about your past, so stay tuned.

      GPS Origins always reports the results for two lineages, which should roughly correspond to the origin of your parents. The test works best for people with DNA from no more than two different places; that is to say, people whose parents are from different places but are not themselves mixed. For people with more mixing, say, four grandparents from various places across the globe, the test will report the midpoint between the four places.

      The next generation of this DNA testing for ancestry will reveal the genetic origins for people with significantly mixed genetic backgrounds.

      If someone with a high percentage (+30%) of Native American ancestry is tested on GPS Origins, the report would reveal a high percentage of the North American gene pool and migration point(s). People with a more diverse genetic mixture may not show gene pools and migration points of origin in North America.

      The test will tell you where your DNA is from and may help you get started on your search to find your birth family and to help you build a family tree.

      An ‘ethnic group’ is considered a group with shared characteristics such as culture, language, religion and traditions, and sees itself or is perceived by others as a distinct community. It is not necessarily genetic and definitions of what is a distinct ethnic group may vary from place to place.

      This DNA test for ancestry tells you where your DNA began. It is more accurate than your ethnicity, which refers to a much bigger group of people that may reside in multiple places. Genetic origin, therefore tells you much more about the smaller group of individuals who were your ancestors.

      The algorithm was developed at the University of Sheffield by the research team of Dr. Eran Elhaik who also developed the original algorithm published in a peer-reviewed paper in the highly respected Nature communications journal (Elhaik et al. 2014. Nature communications). In that article, the authors showed that the algorithm traced individuals back to their country, island, and the village of origins. The accuracy of the test was demonstrated by the DNA signature of ancient Ashkenazic Jews, formed some 1500-2000 years ago (Das et al. 2016. Genome Biology and Evolution).

      This test calculates positions according to your DNA, gene pools, and over 862 reference populations. Occasionally, your genetic location may reside over a pond or river, but don’t be alarmed, it doesn’t mean your DNA has originated in the water but rather that nowadays the river is running very close to the region where your DNA originated. Moreover, since our test establishes a location according to genetic proximity of your DNA and its similarities to various reference populations – you will also see a circle surrounding your data point, which represents a margin of error (or range) where your DNA may have formed.

      The circle surrounding each data point represents a margin of error (or range).

      Our Starter Ancestry Test’s report states " the breakdown is based on four percentage groups: indigenous American, European–South Asian, East Asian, and sub-Sahara African.” GPS Origins’ analysis comes with a manual explaining our process as well as human migration history.

      If you are interested in learning more about your ancestry, please consider GPS Origins. We developed this test with our customers in mind as they requested more details of their past. GPS Origins is a revolutionary DNA test for ancestry that takes you deep into your family history. Traditionally, these tests provide a breakdown of your ancestry and locate parts of your DNA in broad continental sweeps, but nothing specific, not even to the country level. The advanced ancestry test combines the latest genetic research with a new ancestral tracking technique to pinpoint more precisely where your DNA began using the latest technology and algorithms. GPS Origins can pinpoint the town or village where groups of your ancestors from different cultures met—building a vibrant picture of the migration journeys that formed your deep genealogical heritage.

      You will receive a detailed report of your DNA story. It starts with the Human Origin story from Africa- the origin of all humankind- starting 200,000 years ago. It is followed by a story of the formation of Gene Pools (Genetic Origins) some 50,000 years ago, with results showing which are most similar to your DNA. Next, you receive a map with two migration journeys, one from each side of the family, including their subsequent migration stories. The migration routes include ancestral points of your DNA—the last of which includes the period of its formation. Finally, you will receive a summary page with links to external research to help you learn more about your genetic origin.
