Fig. 1: Number of SNPs covered, sampling locations and ages of ancient individuals.
From: Genetic history from the Middle Neolithic to present on the Mediterranean island of Sardinia

a The number of SNPs covered at least once and age (mean of 2σ radiocarbon age estimates) for the 70 ancient Sardinian individuals. b The sampling locations of ancient Sardinian individuals and a reference dataset of 961 ancient individuals from across western Eurasia and North Africa (with “jitter” added to prevent overplotting; see Supp Data 1E for exact locations).
