Like a film more than a portrait – a new DNA model redefines family history

Popular genetic test The company 23andme Bankruptcy filing, what does the future of Ancestry DNA look like?
A team of researchers from the University of Michigan says it will look more like a film than a portrait, thanks to a new statistical model that can be used to watch a new way.
Redefine the family tree
This new statistical method developed by Gideon Bradburd and Michigan University (UM) Researchers Michael Grunds And JonathanIt promises to give a more complete picture of the human lineage. The team calls it a film version of Ancestry, not only your genetic make -up, but where your ancestors come from and how they move to reach where they are today.
The so -called GAIA (Geographical Surname Inference Algorithm) combines modern genetic sequence with old DNA techniques to create a nuanced and unique portrait of the connections of ancestors.
At the beginning of the process, researchers start with a simple assumption: when people move, they usually act locally. Gaia then takes this assumption and combines it with both modern places and genetic structure to create a dynamic picture of the descendants.
This new modern method, Science– The Genetician Svante Pääbo, who won the Nobel Prize, returns to his work in Old DNA. Pääbo has developed groundbreaking vehicles that made the genotype ancient DNA possible.
Thanks to these tools, the UM team was able to monitor the spread of human populations and saw how these populations entered and quit at certain geographical areas at certain points. Gaia can provide a comprehensive family tree that extends for centuries by using population monitoring and movements, as well as modern genetic sequence.

This new lineage model is largely different from the common methods used by many popular companies. Typical personalized compared to the type of report that Gaia can create ANCESTRY REPORT The scope is incredibly small and only provides an instant image of a family tree from a particular place and time.
Most of the time, when you receive an Ancestry report, you will be able to calculate a percentage that reveals something like 50 percent Irish. In fact, it means that you probably have many current relatives, like the second or fourth cousins living in Ireland.
According to the UM research team, your family tree is much more active than this static result, and so is the family tree of all people.
Bradburd said, “Since our genealogyists explode very quickly, you and I should share many relatives at many points over time and this is true for everyone living on the world, Bradburd said. Press release. “We are all interested in each other in an extraordinary way.”
The future of population genetics
Gaia was partially created in response to a call from the National Academy of Sciences to a call that requested it to move away from human population genetics from race -based labels.
In the case of population genetics, racial categories and labels are archaic and often not certain, which leads to false estimates about genetic variation. This is because sharing a racial category or label does not mean that two people are genetically or essentially similar.
A model like GAIA can help to correct this problem by emphasizing how much genetics can change over time in a particular geographical region.
This new method can be used in areas beyond human genetics, including the emergence of viruses, the decomposition of animal populations and monitoring other genealogy.
Currently, the research team in UM is cooperating with scientists around the world. While researchers in Australia are used to find out that the mosquitoes in the South Pacific colonizing the mosquitoes in the South Pacific, the teams in Michigan and Ohio use them to understand the history and disintegration of the Massauga rattling snake.
