a Locations of the three sites on a current map of Portugal. Map drawn in Mapbox Studio using a custom style. b Species identified in 84 samples from levels 6–7 (29–31,500 BP) of Vale Boi, in 95 samples from layers GG to JJ (38–45,000 BP) of Lapa do Picareiro, and 34 samples from chambers 1 and 2 (estimated 50–60,000 BP) of Gruta da Companheira. Overall species distribution is displayed by the pie chart, whereas bar charts show species ratios for separate compartments of the assemblage. Colors are used to distinguish species, as indicated in the legend. c Average fold-coverage of the 20 genes used for SPIN comparing the three Portuguese sites with the modern reference and iron-age material. Coverage was calculated by summing the number of precursors at each site in the global aligned database and is indicated by color using white for no coverage, blue for medium coverage, and pink for high coverage. The values represent the average fold-coverage in 10 amino acid bins for each dataset.
