A surefire way to advance archaeogenetic research

I'll be brief. There are several of the "old guard" of kurganists (steppe hypothesis proponents in general) still alive, and this acts as an inhibitor to the proliferation of other hypotheses and theories. Academia is highly conformist and also low T so nobody wants to risk some conflict with someone else. Everything has to be sterilized and curated. There's one thing that overcomes these though: death. Once the chief kurganists start dying out, which will be soon enough (by 2025 Mallory is 80, Kristiansen is almost 80, Anthony is 70 or almost 70), their absence will replace their previous presence. What this means is that archaeologists, archaeogeneticists et al will simply not account for the theories of the now-dead professors and schoolmarms as something to pay attention to so they won't cross it. Consider it like someone being buried in an unmarked grave. Sooner or later the ground will be trampled by horses. Reserach is moving in different directions already anyway, which is why I am writing this now. An additional way to consider it, is like a dam failing.

Gimbutas is one such example. She's been dead for a while now and, even in the pre-archaeogenetics era, her theories were simply forgotten or fallen out of favor. Nobody cares about academic ideas if they stop being peddled.
