To deepen the subject:
Basically when they say that the total human genetic gradient, which is called cline, or clinal variation, is mostly flat, they are right. But you are also right to question this. Because turns out 98% of human DNA doesn't really do a spinning flying fuck of anything for genetic expression. These are called neutral genetic markers. But if you remove that, oh boy if the noise and differences increase! Too bad a total graph showing this is like nearly impossible to find, everyone seems to use whole-genome for visualizations, and plus you gotta learn how to understand each graph. You'd need to check alleles individually one by one. For example, look how drastically Light Skin Allele of SLC24A5 changes (An allele is a specific "version" of a specific gene):

I guess this also settles the retarded debate on whether japanese are white or not (they're not)

Doing a bit of scientific research

ever noticed how niggers usually smile showing their teeth a lot almost like chimps?

By the way chat, convince older members of your family to try new activities, instead of the same identical things. This is what keeps brains active. Even only doing sudoku can rot brains if it is the only thing you do
