Humans and Neandertals interbred, new method confirms

"Technical objections to the idea that Neandertals interbred with the ancestors of Eurasians have been overcome, thanks to a genome analysis method described in the April 2014 issue of the journal Genetics. The technique can more confidently detect the genetic signatures of interbreeding than previous approaches and will be useful for evolutionary studies of other ancient or rare DNA samples."

I had my DNA sequencing done last year and I am 0.4% Neandertal and 1.6% Denosovian and 98% smart-ass

That is some bad writing. Way to get it wrong, Shawn Raymundo. Weeping

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.

No kidding, makes it sound like they found Godzilla.

RE: Paleo story of the week
I figure if I am going to necro one of my threads, I might as well necro 2.

http://www.sciencedaily.com/releases/201...170341.htm

The basics are these, with increased pCO2 in the atmosphere comes increased [CO2] in the ocean (the brackets mean concentration). And CO2 in water produces carbonic acid, which is bad if you make your shell or structure out of calcite or aragonite (which dissolves in acid), like clams and corals and microrganisms like forams do. The rate of increase today is fairly easy to get at, but what about the past? Ultimately the oceans can act as a buffer and absorb any CO2 that is released, but when the rate of release exceeds the rate at which the oceans can effectively buffer and absorb it, we see a pH drop (among other changes in the climate).

Couple the changing pH with the fact that with warmer climates also comes decreased seasonality and decreased solubility of oxygen in the water, and you have a recipe for another major biocrisis.
