    Scientists recently decoded the oldest human DNA ever, but their findings are changing previously held theories on early human evolution.

    Scientists have recorded the oldest human DNA sequence ever decoded.  Just how old exactly?  400,00 years old.  The new information shows that the bones, found in a cave in Spain, show a mitochondrial genome sequence similar to Denisovans.  And scientists have one word for this info—“irritating.”  Because it raises the question—“how did the Spanish early human species end up with Siberian DNA.” This new older DNA suggests that the evolutionary history of Neaderthals and Denisovans may have involved mixing and been very complicated.  The previously oldest DNA sequenced was 120,00 years old.
