This isn't convincing to me mostly because I'm familiar with what mitochondrial DNA and phylogenetic says. First of all, these are not human bones that they found in Europe. They are the bones of an early hominid species that we
may have evolved from. The oldest actual homo sapien bones ever found are still from east Africa, to my knowledge. Mitochondrial DNA is different from chromosomal DNA in that we get it solely through our mothers. In chromosomal DNA, it's half and half, 23 from our mom and 23 from our dad, but mtDNA is entirely maternal and it also has genetic markers to show periods at which a person's genetic ancestors underwent mutation. Africans show the earliest genetic markers on their mtDNA which is almost irrefutable proof they are the oldest people. Bones are more refutable, because just because the oldest bones we know of today are African doesn't mean we won't find older human bones tomorrow in China or Siberia or elsewhere. However, even if that were to happen, it wouldn't erase the evidence written in our blood (DNA). It's like how the rings on a tree stump when you cut it let's you know how old that tree is. This also doesn't explain the fact that Africans are the only people in the world with no Neanderthal or Denusovan DNA. All other humans have up to 5% Neanderthal DNA but Africans have none. If we developed in Europe, where Neanderthals were mostly found, it would make more sense that we would have all gotten Neanderthal DNA through admixture, but that's not the case.
