Dienekes has been reporting research that has been pushing back the dates for both Mitochondrial Eve, and the species divergence of from chimps/apes.
In the case of the former, we’re talking around 177,000 years ago, and that she may not have even been an anatomically modern human.
In the case of the speciation of humanity, the accepted view had been about 6 million years ago in terms of a split from a chimp-like ape ancestor (with new research suggesting 3.7 to 6.6 million years ago). But further new research puts it at 7 to 8 million years ago, or as far back as 13 million. The same research puts the modern human-Neanderthal split between 400,000 and 800,000 years ago.
