#PaleoGenetics With the largest dataset of prehistoric European hunter-gatherer genomes ever generated, researchers have rewritten the history of our ancestors. They describe a large-scale replacement that may have been caused, in part, by climatic changes that forced people to migrate. ‘With these findings, we can directly support the hypothesis that during the Last Glacial Maximum people found refuge in the climatically more favourable region of southwestern Europe’

Buried near the end of a Guardian article on Svante Pääbo, is this fragment, unaccompanied by any explanation: "..with a specific Neanderthal variant are more likely to feel pain and to therefore age quicker. .."

I am still gathering my list researchers and writers on medicine and molecular biology to follow. If any of you know or know who in the fediverse knows why the Guardian could say "therefore..." I would read with interest. #paleogenetics #paleogenomics

#ancientDNA people: did you know about the "Palaeogenomicists on Mastodon" #PalGoM list? Il looks like a lovely idea, I have just added myself to it :)

@drbarnes

This time they were more careful with their assignations (pic1): "Reads classified as Pyrus and Malus [pear and apple] are marked with a pound symbol, and are probably over-classified DNA sequences belonging to another species [meaning genus] within Rosaceae..."

Nonetheless nice, #Paleogenetics catching up with #Paleobotany:

An article published in the journal "Nature" reports the results of a genetic study on a Neanderthal community that lived in today's Siberia. A team of researchers including Nobel Prize winner for medicine Svante Pääbo obtained DNA from 11 individuals who lived in Chagyrskaya Cave and 2 who lived in Okladnikov Cave.
