Selected “D-statistics” supporting inferences about gene flows
| Statistic | D | Z | Interpretation |
|---|---|---|---|
| D(French, Dinka; Altai, Chimp) | 5.4% | 9.2 | SI 14: Neandertals share more derived alleles with non-Africans than with Africans. |
| D(Han, Dinka; Altai, Chimp) | 7.3% | 11.4 | |
| D(Han, Papuan; Denisova, Chimp) | −7.0% | −9.5 | SI 14: Denisovans share more derived alleles with Oceanian populations than with other non Africans. |
| D(Han, Australian; Denisova, Chimp) | −7.7% | −10.7 | |
| D(Altai, Mezmaiskaya; French, Dinka) | −16.4% | −5.8 | SI 14: The archaic material in non-Africans falls within late Neandertal variation: Non-Africans share more alleles with some Neandertals (Mezmaiskaya/Vindija) than others (Altai). |
| D(Altai, Vindija; French, Dinka) | −7.0% | −4.3 | |
| D(Altai, Mezmaiskaya; Denisova, Chimp) | 13.2% | 5.9 | SI 15: Gene flow between Altai related Neandertals and Denisovans (Denisovans share more derived alleles with Altai than with Mezmaiskaya) |
| D(Altai, Vindija; Denisova, Chimp) | 7.9% | 5.6 | |
| D(Altai, Denisova; 12 Africans, Chimp) | 7.0% | 11.6 | SI 16: Unknown archaic gene flow intoDenisova: Africans share more derived alleles with Altai than with Denisova, a signal that strengthens for fixed derived alleles |
| D(Altai, Denisova; 12 Africans Fixed, Chimp) | 13.4% | 10.0 |
