Admixture between ancient Judean/modern North African date palms and P. theophrasti. (A) Admixture D-statistic and (B) admixture f₄-statistic, both testing whether ancient Judean and modern North African date palms show an excess of shared alleles with P. theophrasti, in which case they are significantly positive. We estimated the D-statistics and f₄-statistics using the following tree: (((test sample, West Asian date palms), P. theophrasti), P. reclinata). The same analysis with P. canariensis as the outgroup is in SI Appendix, Fig. S8.
