Neanderthal to Ust’-Ishim	1.5	1.9	1.6
Neanderthal to K14	1.5	1.2	0.9
Denisova to Australasians	3.5	3.0	3.1
Denisova to MA1	1.2	0.5	0.6
Western Eurasian to Suruí	26.6	28.2	25.2
East Asian to Mamanwa	68.5	–	–
Eastern Eurasian to MA1	17.4	10.8	16.2

NOTE.—Inferred mixture proportions in the admixture graph. Final ancestry proportions in leaf-node populations may be lower if diluted by a second admixture event. The three sets of values are for the primary (Human Origins) data, SGDP, and SGDP restricted to transversions. Exact archaic admixture parameters should be treated with a degree of caution (see Materials and Methods, “Possible methodological caveats”).
