The Metal Age invader of which never was

FTDNA has launched a brand-new “Ancient Origins” analysis, in addition to also I’ve been asked a few times right now what I think of the “Metal Age invader” component in This particular test. Essentially, I share the view of one of the commentators inside the comments here.

FTDNA right now versions Europeans as a mix of hunter-gatherers (Loschbour, La Brana 1 in addition to also Motala), early European farmers (Stuttgart, Iceman, LBK) in addition to also so called “Metal Age invaders” which are based on Corded Ware in addition to also Yamnaya samples – so the latter can be what we more typically call “steppe admixture”. (Plus they add non-European admixture in case someone has the idea very evidently.) This particular type looks crude for our present-day standards, in addition to also their results look very different through what I’ve seen here in Davidski’s analyses or in different ancient-DNA calculators on Gedmatch, as their inferred proportions of steppe admixture are much lower, about half of of which inferred by others. in addition to also moreover to me the idea looks completely wrong of which FTDNA suggests of which I (1/4 Italian, strong southwest European component) have more Metal Age invader admixture than my fully East Prussian grandmother.

Indeed, any Early Bronze Age Steppe-inspired component should peak at 40-50% amongst Northern in addition to also Eastern Euros. This particular apparently doesn’t. Why? No idea.

I know better than almost anyone else of which there’s no such thing as a perfect ancestry test, in addition to also FTDNA has every right to offer an experimental analysis to its clients, so let’s leave the idea at of which. nevertheless if you want to see what an ADMIXTURE test which has a half-decent Yamnaya component looks like, then check out my attempt [HERE]. These are graphs through the linked blog entry showing inferred levels of Yamnaya-related ancestry proportions for Europeans in addition to also West Asians.
