A PAR1 neighbor-joining tree for human (H), Neanderthal (N), Denisovan (D), and chimpanzee (C) sequences. Internal branch supports of 100 bootstrap samples are shown in green rectangles. B Substitution spectra for the Neanderthal, Denisovan and human PAR1. C Nucleotide heterozygosity for 10 kb windows of PAR1 in Neanderthal (NEA) and Denisovan (DEN) sequences, measured as per site heterozygosity H. Numbers of polymorphic sites used to infer H values are presented in the parentheses. D Spearman coefficients for correlations between diversity at the 10 kb scale, for archaic individuals and humans (HUM). Crossed-out coefficients are non-significant (p > 0.05). We only consider 10 kb regions with more than 2500 callable sites
