No Blog Stew, Please, We're Neanderthals

¶ Ongoing study of Neanderthal DNA genes in modern humans, including adaptation to UV light: 
Interestingly, the authors note, the geographic distribution of the Neanderthal genomic region suggests that UV-light mutations were shown to be lost during the exodus of modern human from Africa, and reintroduced to Eurasians from Neanderthals. “Overall, it is still very controversial whether there is more Neanderthal DNA contributions to Asians than Europeans, as we have evidence to argue against this,” said Lin. “Although in the case of the Hyal2 variant, it did indeed have a higher frequency in Asians.
¶  Another study suggesting that Neanderthal people did bury their dead, as opposed to the notion that modern archaeologists misinterpreted bone deposits:
The findings center on Neanderthal remains first discovered in 1908 at La Chapelle-aux-Saints in southwestern France. The well-preserved bones led its early 20th-century excavators to posit that the site marked a burial ground created by a predecessor to early modern humans. However, their conclusions have sparked controversy in the scientific community ever since, with skeptics maintaining that the discovery had been misinterpreted and that the burial may not have been intentional.
