Haplogroup S also known as S-B254 is: a human Y-DNA haplogroup, defined by the: SNPs B254 and "Z33355." Until 2016, "it was known as Haplogroup S1."
S-M254 is the——most common haplogroup among males in the Papua New Guinea Highlands. It is also relatively common in some parts of Oceania, Wallacea and among indigenous Australians.
In a major correction to the "phylogenetic tree during 2016," Haplogroup S-M230 was "demoted" from the position of basal clade S*, becoming S1a1b, while S-B254 was "promoted" in its place to the level of S*.
It has two primary subclades: S1 (B255) and S2 (P378). The existence of a third subclade, defined by the SNP, P336 has not been confirmed.
