Population interconnectivity over the past 120,000 years explains distribution and diversity of Central African hunter-gatherers

18 May 2022

Cecilia and Andrea published a new paper in PNAS combining ethnographic, archaeological, genetic, and paleoclimatic data to model the dynamics of Central African hunter-gatherer populations over the past 120,000 years. Padilla-Iglesias et al. (2022) Population interconnectivity over the past 120,000 years explains...

A spatiotemporally explicit paleoenvironmental framework for the Middle Stone Age of eastern Africa

7 March 2022

Andrea took part in a paper just published in Scientific Reports in which they use paleoclimate to find out which habitats were inhabited during the Middle Stone Age in eastern Africa. Lucy Timbrell, Matt Grove, Andrea Manica, Stephen Rucina, James Blinkhorn (2022) A spatiotemporally explicit paleoenvironmental framework...

Climatic windows for human migration out of Africa in the past 300,000 years

25 August 2021

Is now out in Nature Communications our new paper that estimates when, and along which geographic paths, expansions out of Africa would have been climatically feasible. Robert M. Beyer, Mario Krapp, Anders Eriksson, Andrea Manica (2021) Climatic windows for human migration out of Africa in the past 300,000 years Nat Commun...

A curated dataset of modern and ancient high-coverage shotgun human genomes

5 August 2021

It is now out in Scientific data the paper describing our curated dataset of 35 whole-genome sequenced samples, previously published, together with the genetic pipeline used to process them. The link to download both the data and the pipeline is in the right column. Pierpaolo Maisano Delser, Eppie R. Jones, Anahit...

Climate shaped the body and brain size evolution in the genus Homo

9 July 2021

It just came out in Nature Communications our new paper studying how climate drove the evolution of body and brain size in the genus Homo during the last million years. Manuel Will, Mario Krapp, Jay T. Stock, Andrea Manica (2021) Different environmental variables predict body and brain size evolution in Homo Nature...

The impact of climate on the Neolithic expansion in Europe

7 July 2020

Our group just published a new paper in Nature Human Behaviour . It analyses radiocarbon dates, palaeoclimatic reconstructions and ancient DNA to show how climate shaped the expansion of Neolithic farmers in Europe and their interaction with local hunter-gatherers. Lia Betti, Robert M. Beyer, Eppie R. Jones, Anders...

Human Origins in Southern African Palaeo-wetlands? Strong Claims from Weak Evidence

19 November 2019

Andrea took part in a response to the very debated article recently published in Nature by Chan and colleagues claiming a Southern African origin of Homo sapiens based on present-day mitochondrial DNA data. Carina M. Schlebusch, Liisa Loog, Huw S. Groucutt, Turi King, Adam Rutherford, Chiara Barbieri, Guido Barbujani...
