This will be a thread for ancient and modern population genetics.
This topic is something I have an great interest in and hope to spread it further. I think its important for guys in our sphere to be especially knowledgeable about this field given the prevalence of "academics" who lie about ancient cultures/people and their relations to modern groups. Are you really racist if you don't know the exact Natufian levels of every main jewish group?
This first post will mostly be about how to get started using G25 and Vahaduo if some of you haven't used it. "Vahaduo App Gallery" is a collection of tools for admixture and PCA analysis. You can run models and create 2D and 3D graphs/PCA charts. This is the front page https://vahaduo.github.io/
From the front page "Admixture JS" is what you use to make models and "Global 25 Views" is where the different premade PCA charts are. You'll need to go down to "G25 Download" and click "download all spreadsheets" to get the coords of all the ancient and modern populations to model with. https://vahaduo.github.io/g25download/
Scaled coordinates are the ones that are the most accurate. Unscaled will give usually give you a few percent (1-3) of some foreign admixture that isn't actually apart of your ancestry like Jomon, Polynesian, or even Papuan. You can get your own G25 coords by first getting a DNA test like 23andme or AncestryDNA then downloading your raw data from their site once you've gotten your results back. You'd then email Davidski from Eurogenes https://eurogenes.blogspot.com/2019/07/g...25_12.html and pay 12 dollars, but recently IllustrativeDNA has offered one free G25 coord id you sign up. Their coord is exactly the same as the one you'd get from Davidski himself. https://illustrativedna.com/
When you use "Admixture JS" you'll just copy and paste the coordinates of your choice under the source and target tabs. It will create the closest mixture to the target from the available sources. This means that others can omit certain sources to skew results. Generally anything with a distance that is less than 3.0% or 0.03 is decently close. https://www.exploreyourdna.com/calculateurs.aspx has premade calculators that are easy to try out. A few examples I've made: https://imgur.com/a/VgQcilT
If there is any particular population that you all would like to know about then I will make a post about them.
