This is what I love about science. The more you know, the less you know. And the less you know, the more you want to know.

I should write this down.

TheMysteriousStranger: Paleoanthropologist John Hawks has a good look at this news:
The Denisova-Sima de los Huesos connection

I'm glad he makes the point that while the Sima have "Denisovans like" mtDNA, "the difference between Sima and Denisova sequences is about as large as the difference between Neandertal and living human sequences. It would not be fair to say that Denisova and Sima represent a single population, any more than that Neandertals and living people do."

and that he argues against "straight line" thinking. I wonder how the Creationists will make complete nonsense of this discovery if it comes up on their radar. P Z Myers addressed their confusion about phylogeny in this post. le dge-is-a-dangerous-thing/

where they were dumbfounded that "In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other"

The conceptual problem is that many conceive of genetic change only happening at speciation rather than preceding it. I.e.

Phylogeny of the great ape family, showing the speciation of human (H), chimpanzee (C), gorilla (G) and orang-utan (O). Horizontal lines indicate speciation times within the hominine subfamily and the sequence divergence time between human and orang-utan. Interior grey lines illustrate an example of incomplete lineage sorting at a particular genetic locus-in this case (((C, G), H), O) rather than (((H, C), G), O). Below are mean nucleotide divergences between human and the other great apes from the EPO alignment.
