Extended Data Fig. 3: Genetic diversity in ancient and contemporary populations.

Diversity of the ancient population (n = 3) and different random subsamples (n = 3) of individuals from the contemporary populations, Andújar and Doñana, considering both transitions and transversions (a) and transversion only (b). Points represent the mean and bars, although not always visible, and represent the standard deviation calculated over 10 kb windows using 100 iterations.
