Neanderthal genes even less likely to be within us

at Genes and Demons, based on a New Scientist's article:

Vindija Neanderthal genome is half-way into full sequencing and, this is the important part, some speculations can already be discarded:

  1. Neanderthals did not have the microcephalin gene
  2. Neanderthals did not have the increased fertility variant of Icelanders
  3. Neanderthals were lactose intolerant
The full genome will take some other two years or so to be finished but these advanced conclusions again support the model of no (or extremely low) introgression from our native european cousins. There is nothing yet to support Neanderthal admixture in any degree, though, of course the possibility will likely remain open even after full sequencing.
