New paper alert 🚨
A study led by #CPGSthlm researchers found DNA from a bear in 9.6k year old lake sediments. This potentially rewrites the history of brown bears in Scandinavia! 🧬🐻🐾🏔️🧊

New preprint led by Hrushikesh Loya, me, and Simon Myers where we introduce GhostBuster! www.biorxiv.org/content/10.6...
The idea is to find all the different ways a target individual relates to reference groups in genealogies, to "bust the ghosts" in our ancestry.

Can you believe that until now there were more genomes sequenced for the woolly mammoth than for living African elephants?
Today, we bring you the first genomic, continent-scale analyses of 232 high-quality genomes of both species, the savanna and forest elephant.

Muchísimas felicidades María!! Más que merecido! ❤️
Congrats Kevin!!
Very excited to share our study of an ancient environmental genome extracted from lake sediment! It originates from a brown bear that lived around 9,600 years ago close to the last ice-sheet remains in northern Sweden, and has an unexpected mitochondrial haplogroup. 1/7 www.pnas.org/doi/10.1073/...
Summary chart showing mean and standard deviation of carbon and nitrogen isotope values from Swifterbant compared to human and faunal values from the Mesolithic site of Hardinxveld. One group of cows and sheep at Swifterbant displays a diet similar to humans and dogs, suggesting they were being managed by humans.
When did people in northern Europe first adopt animal husbandry? #NationalFarmAnimalsDay 🏺 #Archaeology
Isotope analysis of animal remains from Swifterbant 🇳🇱 suggests livestock management was practised in the Dutch wetlands over 200 years earlier than expected.

A few years ago, using palaeoproteomics, we identified a tiny hominin bone from Denisova Cave and named it Denisova 17 (D17).
A rather unremarkable sliver.
At the time, I wondered, could it be Denny’s sibling (the Neanderthal/Denisovan hybrid we had just reported)?
Well, turns out: no. 🧵1/4

New paper alert 🚨
Researchers at #CPGStlhm have analyzed ancient genomes from an Islamic cemetery in Ibiza (950–1150 CE) 🏖️
They found a highly diverse community with ancestry from Europe and North Africa!

Overview of Admixture results based on genome-wide SNPs supporting four giraffe species (top)—northern giraffe (Giraffa camelopardalis), the reticulated giraffe (G. reticulata), the Masai giraffe (G. tippelskirchi), and the southern giraffe (G. giraffa)—and 7 subspecies (bottom). Colors correspond to (sub)species membership. Map of sub-Saharan Africa shows the geographic ranges of each giraffe (sub)species where colors correspond to (sub)species colors from Admixture results.
Giraffes have long necks and a long history of scientists debating their taxonomy! 1 species with 9 subspecies had generally been accepted, but whole genome data from 50 giraffes from all previously recognized subspecies support 4 species and 7 subspecies! #2026MMM doi.org/10.1016/j.cub.2021.04.033

Really happy to share our new preprint on the co-occurrance of Y.pestis and Erysipelothrix spp. during prehistory. 🔥🔥🔥
In the study, we find the earliest evidence to date of Y.pestis in Southern Europe and 60 new Erysipelothrix genomes spanning 20k years 🦠🐄🚶♂️⌛

The story the evolution of height in populations of Europe has been a bit of rollercoaster, veering between natural selection or admixture with populations who had a higher genetic propensity to be taller by chance. This preprint goes back to natural selection...

Excited to share our work on #AncientRNA from alcohol-preserved lungs, recovering the oldest human RNA virus genome (an 18th-century rhinovirus). Our study shows that viral RNA remnants persist in centuries-old tissue, opening new ways to study virus evolution and historical disease #Paleovirology🫁🦠

We sequenced #ancientRNA from an 18th-Century human lung and recovered a rhinovirus genome. Take a look at our preprint. Feedback welcome.

Incredibly important story that everyone should read.
These are not disorganized lone actors, but well-funded and powerful networks to be treated as serious threats.
They are using our work to push a eugenicist and racist agenda that is scientifically invalid and morally reprehensible.
