Adaptation is typically studied by comparing modern populations with contrasting environments. Individuals persisting in the ancestral habitat are typically used to represent the ancestral founding population; however, it has been questioned whether these individuals are good proxies for the actual ancestors.1 To address this, we applied a paleogenomics approach2 to directly access the ancestral genepool partially sequencing the genomes of two 11- to 13,000-year-old stickleback recovered from the transitionary layer between m
