I think this confused me.

				Understanding human genetic diversity in Africa is important for interpreting the evolution of all humans, yet vast regions in Africa, such as Chad, remain genetically poorly investigated. Here, we use genotype data from 480 samples from Chad, the ...

I used the supplementary data from that study to make claims on the Y-DNA discussions from earlier and it is roughly correct on the haplogroup R1b. Those particular uniparental claims coincide with the incursion of pastoralists, highly correlated with the Chadic linguistic group directly or in the dynamic influx of migrational capacities flowing into similar spatio-temporal dimensions. 
The autosomal claim about 30% European DNA is ridiculous. The study from 2016 that I need to mention has absolutely no signature resolution and did not overemphasize European affinity, majorly highlighted Near Eastern association, and laid weight on bottlenecks deep in history synonymous with the Horn of African groups, despite it only being a considerable broad perspective.
The LBK European Neolithic farmer affinity was only using ancient samples from Europe-proper. The f3-statistic used difficult but interesting reference sample sets, and you had Amhara getting way stronger results of that kind. Are Amharas over half European Neolithic farmer now? Letās move on from this and stop taking anything pertaining to autosomal DNA from Wikipedia referencing studies at face value when they go against basic common sense.
I donāt want or need to get into the technicalities of the f3-statistics since it goes into separate things that entail other deeper affinities given the constraints compensating alignments into deeper drift and different layers of affinities, but ultimately the study never claimed what you quoted, and on top of the study lacked the information I do have today. 
I've already stated what they contained and the study literally agrees with me within the limits of what it knew at the time giving broad associations with a lot of constraints, at the same time no actual resolution, which I stated to you (that region) had its own regional-local highly ancient endemically differentiated genetic process, separate from Berbers or any of that northwest African while at the same time carrying interesting affinity with northeast Africans with ultimately having a deep relationship to the tapestry indirectly (interesting association with northeast Africa, so directly but not so obvious) of the two sides in a very non-straightforward way, but again, a respective region in that conversation where extrapolating is a false model that does not reflect the deep formations there.
Now that you are less confused, I would appreciate you re-read my material and trust it since I am getting a little annoyed you treated some made-up Wikipedia post that has no grounding in reality as possibly symmetrically true as my posts thinking I waste time writing to you or you're trolling me entailing you're neither thinking my posts are serious enough for consideration which is just insulting weighing some random ignorant claim from Wikipedia that goes against what I time and time again said, which really indicates on what scale my post lies in your value-chain in a discussion you pretend at least on the surface to value my input, yet all along bellow that of made up rubbish Wikipedia sentences. Don't do this next time. 
I am going to assume the best of you and just think you did have no idea about the topic itself, despite me telling you information contrary to that quote and you pretending to follow along (to some extent rubs me kind of the wrong way too). But anyway, I have answered your question and would like to move on from this topic. I could have responded with a laughing emoji and moved on without a response but I gave you the courtesy of responding back so next time this does not happen. Consequentially this is an insult to me because that last post of yours basically tells me you wasted my time.
