By the time the descendants of the Sintashta reached Iran, for instance, they were already over 50% BMAC and less than 50% Sintashta. They were already brown by the time they "bleached" anyone. Furthermore, they were not descendants of Europeans. Sintashta were descendants of Indo-Europeans, steppe people. The Europeans are the EEF longhousers who carried G2a. They are the indigenous people. They got raped and created the Gargoyleern "white european" mutt who is actually just a massive rapebaby, more so than any phantom. Europeans basically got raped into extinction by the Steppe people and Gargoyleern Europeans are their mutt rapebabies. G2a is basically non-existent in Europe, but the native mtdna haplogroups of the Europeans are still dominant there. In Iran and India, the native J and H/T haplogroups still hold strong. This is because phantoms are of superior Zagrosian blood, who were not weak enough to get extincted like the Europeans. The Sintashta steppe people did regardless leave a large genetic imprint. Zagrosians actually left an enormous genetic imprint on southern Europeans as well. Europeans are actually the most raped people on the planet
