A map of 7000+ ancient DNA samples from a talk given by Dr. David Reich at the 2019 Allen Frontiers Symposium. This is from an upcoming study of the ancient origins and distribution of the CCR5-Δ32 HIV resistance allele.

Notice there are many samples from regions that have not been published yet:
Mesopotamia, Upper Egypt, the Sahara, Northwest and Central India. There is a very large concentration of samples from the Levant.
We can't be 100% certain that the blue dots are all ancient samples (though, some of them are clearly from the sea!) and that all of these have yielded DNA. 293 ancient Philistine and Canaanite individuals were sampled, yet only 11 yielded DNA, so these blue dots may represent all of these 293 samples. Notice too that only some areas have black dots that show individuals definitely lacking the CCR5-Δ32 allele.
Maybe someone here knows if these blue dots are all ancient samples, and if they are, did these samples all have successful DNA extraction?
It seems that CCR5-Δ32 originated among the Samara Culture hunter-gatherers 7000 years ago along the Volga, and their successors the Khvalynsk Eneolithic.
