    Lightbulb Plot of WHG & S. Eurasian based on K8 Spreadsheet

    I plotted some K8 spreadsheet populations to aid in visualization of the spreadsheet.
    The reason I used WHG and S. Eurasian, is that they are contrasting based on FST (good spread), and that they have a positive North and East geographic correlation, respectively.
    Thus, I felt that the plot was informative in that the spatial positioning of the populations on the plot, appears to be consistent with their respective geographic location.
    A more complete picture can be formed, if another plot is made using Near Eastern on the y axis, and E. Eurasian or ANE on the x axis, since there appears to be a positive North and East correlation, respectively, with those components as well. The graph may appear too clustered if E. Eurasian isused, due to the relatively low standard deviation in E. Eurasian among many of the K8 populations.
    I may be able to add some of the other members who posted their results to the plot(s) over the weekend, time permitting.
    Observations: Although some populations seem spatially close toeach other on the plot, they my not be if a 3rd dimension (z axis)is added representing for example E. Eurasian.
    The Iranian population which is geographically located between Indiaand the Caucuses, according to the plot shows also to be genetically (based on WHG and S. Eurasian) near Afghan Tajik, Afghan Pashtun, and Afghan Hazara.However, if a 3rd dimension is added to the plot, representing E.Eurasian, the spatial distance to the latter (Hazara) would increase. [IMG][/IMG] Edit: Certain populations were not added, because they caused the plot to become too clustered due to their similarity to other populations

    Building on the previous post, I plotted the averages of some of the K8 populations. I would like to emphasize that the spatial distances are indicative of genetic distances only for populations that do not have significant amounts of other components, such as NE, E Eurasian, ANE, etc. I will be posting another plot to cover NE and ANE or E Eurasian over the next few days. By viewing both plots side by side (the ones posted so far and the one that I will be posting later), a good idea of genetic distance can be obtained for populations that do not have significant admixture in components outside the ones on both plots (a total of 4 components will be shown on 2 plots). PM me with your results if you would like to be added to the plots.[IMG][/IMG]

    If possible, maybe you should make a single icon for regions. You could also make icons for ethnic groups from the same region the same color. It's hard to keep track what region all the different icons come from.

    It will become very difficult to tell one group from the other by looking at the legend, since they will all be the same color.

    I'll work on it.

    Would it be possible for you to add Iraqi and Iranian Jews as well as the two Iraqi Mandaeans? Here are their West Eurasia K8 results.

    I would much rather see a graph based on ENF, WHG, and ANE, not South Eurasian, because we don't know what South Eurasian is while the other three are based on ancient genomes. A WHG vs ANE, ANE vs Near eastern, and Near eastern vs WHG for west Asians and north Africans would be interesting. There's a string of WHG in north Africa which may be pre-Neolithic.

    S. Eurasian appears to be an ASE very heavy component, as it appears to peak in the Malay population. While not relevant for European to European comparisons, my intent was to be able do a comparison with S. Asians as well, thus the relevancy.

    I do plan to plot a graph of NE vs ANE. With the 2 plots, the one I have posted and the one I will be posting, the following regions' admixture will receive ~ 90 to 99% coverage depending on the population:

    1- Europe;
    2- W Asia;
    3- S Asia, with the exception of E Eurasian heavy populations such as Uzbek, Turkmen, Hazara, etc.

    Therefore, to visualize genetic distance, for comparing the aforementioned, you can look at the 2 plots.

    The 2 plots will not be very useful for various populations within the following regions, to name some, since they contain significant components of either E Eurasian, SSA, Oceanian, or Pygmy:

    1- E Asia
    2- N Asia
    3- Parts of S Asia and S Central Asia mentioned above
    4- Africa
    5- Australia

    Here is the K8 component, ANE vs. NE plot for various populations, including a few Anthrogenica members: [IMG][/IMG] EDIT: I will be posting the population means for this plot later. This plot in combination with the previous plot, WHG vs. S. Eurasian can be used to estimate the genetic distance between 2 populations, by adding the linear distance between the two from both plots, subject to the condition that the two populations compared do not have any significant E. Eurasian, Oceanian, Pygmy, and Sub Saharan components.

    That graph matches PCAs of west Eurasia. It seems the pops that changed west Asia after the early Neolithic had lots of ANE, little to no WHG, and anywhere from 0-70% ENF. The pops that changed Europe after the Neolithic had alot of WHG and ANE, and little ENF.

    West Asians look like a mix of something Lezgin-like and Bedouin-like, and Europeans look like a mix of something Stuttgart-like and something Lithuanian-like. The Lithuanian-like pops from bronze age Europe were probably a mix of steppe pops and east and northern hunter gatherers, and spread their genes from east-west and north-south.

    The Lezgin pops from Neolithic or bronze age west Asia were probably a mix of something originally from the steppe or south-central Asia, which mixed and became mostly near eastern, and spread from north-south.

    It might not be random that an ANE-rich pop from west Asia and an ANE-rich pop from Europe both spread their genes at around the same time. They both could have gotten their ANE from the same Mesolithic source, one mixed with WHG-rich pops and one mixed with ENF-rich pops.
