 Project objective

As global climates warmed ca. 10,000 years ago came a remarkable convergent transformation of human lifestyles that occurred independently in multiple continents and human populations. This transition from hunter-gatherer subsistence to food-production catalysed large-scale population growth, offering the opportunity for increased rates of adaptation, but also rapidly presented a large number of independent human populations with a new evolutionary challenge. This project will use ancient population genomics—the only way to directly reconstruct human genetic evolution—to study whether evolutionary processes during the agricultural transition differed in differed regions. Which genomic adaptations were associated with the agricultural transition? Did adaptation to hunter-gatherer and agricultural lifestyles act on similar genetic architecture in different instances? To which extent did adaptation in domestic dogs—the only species domesticated prior to the agricultural transition—occur in convergence with humans? To answer these questions, the project will generate ancient genomic data from pre-agricultural and early agricultural populations from multiple human- and domestic dog populations from Africa, Central America, and Southeast Asia. This will be achieved with direct sequencing as well as a new human ~850,000 SNP capture panel designed to avoid bias towards Eurasian ancestry. We will also develop new computational methods robust to the challenges posed by ancient genomes to identify adaptive admixture, analyse copy number variation, test continuous population models, and statistically assess convergence in the genomic architecture of adaptation. Leveraging cutting-edge ancient genomics and two model organisms for the genomic basis of phenotypic variation, this project aims to reconstruct the universal evolutionary phenomena underpinning a watershed evolutionary episode that shapes global biodiversity and the human condition to this day.
