The Science

Developed in England at the University of Sheffield by a leading population geneticist, GPS Origins African Edition offers incomparable visibility and insights into African ancestry. The technology behind the test assumes everyone is mixed from different gene pool sources. This is starkly different than other DNA tests that suggest all humans branch from just three or four populations that changed over time.

GPS Origins uses autosomal DNA inherited from chromosomes 1-22 that are more sensitive to the genetic signature of your closest ancestors. The African Edition leverages 41 gene pools to trace your DNA—15 of which are specific to the African continent.

How does this test differ from other DNA tests for ancestry?

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.

What kind of technology does this ancestry test use?

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 80,000 of your autosomal markers (SNPs) and compares them with the distinctive mutations in the gene pools of 1,000+ reference populations. This pinpoints the places and times where your DNA last changed.

How accurate is the test?

The level of accuracy depends on your family history. If your parents are from the same place and share relatively homogeneous gene pools, the test can trace both their DNA signatures to their country of origin 81% of the time. GPS Origins correctly predicts at least one parent to the correct country of origin 96% of the time. If both your parents are unmixed, GPS Origins can predict migration pinpoints to the correct country 90% of the time.

In a study of people from across the world, the migration routes generated from 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 they came from, the test will place your DNA signature within 50 miles of its true origin, and often closer.

Your results show the origin as a pinpoint on a map. Any margin of 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.

Note that the results do not necessarily predict your residential address, but rather, a more broad origin of your DNA’s signature, showing the last places where the signature was significantly modified.




Can I use an existing DNA test for ancestry? Do I need to take another one?

It depends on the test you have already taken. You can upload results from 23andMe, Ancestry.com, National Geographic Geno 2.0, or the Family Tree DNA Family Finder; we can analyze them with our GPS Origins tool to provide the full report of where your DNA began. If your previous DNA test was a Y-chromosome test or Mitochondrial DNA (mtDNA) test, it is not compatible, and you will need to purchase the GPS Origins DNA test.

If I already have a DNA test why should I order the GPS Origins ancestry test?

While we accept results from other companies, we recommend using the GPS Origins test. The GPS Origins DNA test includes many unique markers that cannot be found in other commercial tests.  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.


What is the GPS Origins DNA test for ancestry?

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 41 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.

How does the GPS Origins ancestry test work?

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 1,000+ populations with known geographic locations to identify the place where it began about 1,000 years ago.

We have identified 41 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.

What does the GPS Origins report include?

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!

What is a Gene Pool?

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, 41 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.

What is a Reference Population?

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 1,000+ reference populations in its database when calculating your results. This large number of reference populations, obtained from publicly referenced datasets, along with the 41 gene pools helps deliver the accuracy in your GPS Origins results.

View Reference Populations

What is a Migration Pattern?

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.


Will GPS Origins tell me where my ancestors originated?

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.


Where can I find a list of terms and their explanations relating to my DNA test for ancestry?

For your convenience, we've created a glossary with explanations of some of the most common terms you're likely to come across during your DNA test for ancestry.

How will the GPS Origins DNA test help me with my family history?

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.

Why would my GPS Origins test results be different than my siblings’?

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.

What if my family history indicates we have been in one area for a very long time and my results show I am connected to a dramatically different area?

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.

I am mixed race. What will the GPS Origins test results tell me?

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 a person with a great deal of Native American ancestry tested their DNA through GPS Origins, what would be reported?

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.


I am adopted. Can GPS Origins help me discover my birth family?

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.


What is the difference between my ethnicity and my genetic origin?

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.

How do I know my GPS Origins results are accurate?

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).


What if my location point is sitting over a body of water?

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.


What are the circles surrounding my location point on the map? Why do they differ in size?

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


What is the difference between GPS Origins and HomeDNA Starter Ancestry Test, which is available in U.S. stores?

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, DNA tests for ancestry 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.

What is included in the GPS Origins kit?

Your test kit includes an order form, instruction manual, four (4) buccal (cheek) swabs, a DNA Sample envelope and a bar coded return envelope.


How can I tell which migration route corresponds to my paternal line and which corresponds to my maternal line?

Because this test is autosomal, paternal and maternal lines cannot be distinguished by name. But you can be sure one is your maternal line and one is your paternal line. Most of our customers are able to deduce which is which based on knowledge of their own family histories.


Can I get a hard-copy version of my results?

Due to the interactive characteristics of the report, results are online only.
