"#Direwolves dominated southern Canada and the United States, according to Julie Meachen, a paleontologist at Des Moines University who worked on the #ancientDNA project. And they outcompeted gray wolves, being 25 percent bigger and possessing massive teeth and jaws. They hunted horses, bison and possibly mammoths. When many of those prey species became extinct — probably in part because of human hunters — the dire wolf may have been doomed, and the gray wolf swept down from northern Canada and Alaska to fill the ecological void."

🚨 Last day to register for our virtual speed-networking event between PIs and young researchers (MSc/PhD/Postdocs)! 🚨

When? Wednesday April 9th 11.00AM-01.00PM CET. Registration deadline: April 2nd. Grab your slot!

For more information and registration, check out the following google form:

Google DocsSpeed networking between PIs and young researchers - April 2025 editionInterest and registration form for PI speed networking for April 9th, 11:00 AM - 01.00 PM CEST The following PIs are open to meeting with interested junior researchers (prospective masters, PhDs, postdocs, etc.) to discuss anything under the sun (but mainly background, research interests, info about the lab environment/supervision styles, potential projects etc.) -- This is meant to be an informal chat, like those you can have during a conference rather than an interview or anything like that. Here is a list of the PIs participating and some brief information about them: - Assoc. Prof. Martin Sikora (University of Copenhagen, Globe Institute, https://globe.ku.dk/research/geogenetics/sikora-group/) - Dr. Lucy van Dorp (University College London, Genetics Institute, https://www.ucl.ac.uk/~ucbpvan/). - Dr. Alexander Herbig (Max Planck Institute for Evolutionary Anthropology, https://www.eva.mpg.de/archaeogenetics/research-groups/computational-pathogenomics/) - Assoc. Prof. Verena Schuenemann (University of Basel, https://www.iem.uzh.ch/en/research/paleogenetics_group_schünemann.html). - Prof. Ludovic Orlando (Université de Toulouse III, Faculté de Médecine Purpan, https://cagt.cnrs.fr/ages/) - Prof. Nicola Segata (Università Di Trento, http://segatalab.cibio.unitn.it/contacts.html) - Assoc. Prof. Michael D. Martin (NTNU University Museum, https://www.ntnu.edu/employees/mike.martin) You can sign up to talk to more than one PI. However, to allow most participants to meet with the PIs they are interested in, we ask you to select two first choices. When assigning people to the PIs time slots we will prioritize the people that have expressed to meet a PI as a first choice over people that have not. Slots related to the two first choices will be allocated on a first-come-first-served basis. Each chat with a PI will last roughly 12/13 minutes. We will send details of how to attend in a follow up email prior to the event confirming who you will talk to and roughly when. Registration closes on Wednesday April 2nd. Data protection: Please note that submission to Google Forms results in data being stored on Google Servers including those located in the United States. If at any point you wish your responses to be removed from use of the SPAAM community, please contact a member of the steering committee for removal of your personal data.

"The group likely responsible for the Anatolian branch of the Indo-European languages did not share the same genetic makeup as the Yamnaya. Instead, it descended from a distinct but related population, which they identify as the Caucasus–Lower Volga (CLV) group, preceding the Yamnaya and forming part of the earlier expansion of Indo-Anatolian speakers."

“Genomes from more than 400 individuals suggest that the Yamnaya — Bronze Age herders from the steppes of present-day Russia and Ukraine — emerged along the northern shores of the Black Sea. The findings are published on 5 February in Nature.” #DNA #ancientDNA #isogg #Nature #geneadons

If you like thinking and learning about human prehistory, you'll like this interview with geneticist David Reich. Two hours on what research tells us about human origins, how modern humans relate to Neanderthals and Denisovans, ancient DNA, ancient epidemics, admixture, how genetics informs archaeology, and the spread of the Yamnaya from the steppes.

The DNA of 'Thorin,' one of the last Neanderthals, has been sequenced, shedding light on inbreeding and 50,000 years of genetic isolation. This discovery paints a vivid picture of Neanderthal decline, offering new insights into their final days and their legacy in our genome. #Neanderthals #AncientDNA #HumanEvolution
