See Russia, Kazakhstan and Siberia, have cold, dry, or frozen soils (permafrost), which supposedly preserves bone collagen and genetic material for millennia. This is why we have many high sample sizes in these locations, dating back to the Mesolithic period. In contrast, see India, Iran, Afghanistan, and southern Central Asia have arid to subtropical climates, with extreme heat and large humidity fluctuations. The heat accelerates the hydrolysis and oxidation of DNA, destroying the genetic strands and leaving the skeletons "sterile" for paleogenetic analysis, am I correct?

Is this the reason for the lack of samples in these locations? Isn't there an alternative? Do we simply accept that we will never have a decent sample size from these locations? Haploautists bros, its over?

I don't deny that the climate of these places is influential, but these idiots are incompetent. Did you read that disgusting "study" that the Iranians did to prove 3,000 years of continuity on the Iranian plateau? The sampling was so shitty that it was practically restricted to the Alborz Mountains without any sampling of the central Iranian plateau and without addressing periods prior to the Persian Empire. What the hell?! Imagine the absence of presenting this garbage as the conclusive proof of 3,000 years of continuity in a single area

Archaeogenetics should be restricted to Western countries. Period.

Last week I was reading a paper from China and the database was restricted for some reason, lol.

Yes, it's basically correct. We will never have that many samples from the hotter regions.

I would imagine that climate can choose which technique for sample might be best, this articles mentions the technique for sample of micromorphology, a technique that examines sediments under a microscope to establish the integrity of the layers. This key component of the new chronology helped establish that there was a consistent accumulation of sedimentary layers over a long period though this might be more interest to anthropologists or something like that
