Genetic characteristics of the Levant_ChL. a The statistic f₄(Levant_ChL, A; Levant_N, Chimpanzee) demonstrates a close relationship between the Neolithic and Chalcolithic Levant populations, as the Levant Neolithic shares more alleles with the Levant Chalcolithic than with any other populations. b The statistic f₄(Levant_N, Levant_ChL; A, Chimpanzee) shows an asymmetrical relationship between Levant_N and Levant_ChL and other ancient West Eurasian populations. The statistic is most negative for populations from Iran and the Caucasus, indicating that Levant_ChL shares more alleles with them than does Levant_N. c The statistic f₃(Levant_ChL; Levant_N, A) tests for signals of admixture in Levant_ChL. Negative f₃-statistics indicate that the Levant_ChL population is admixed. Populations from Iran and the Caucasus produce the most negative statistics. The estimated statistic ± 3 standard errors is indicated
