Until the SNP/UEP marker M293 was discovered in 2008, the members of the subclade were indistinguishable from other components of the paragroup E1b1b1* (also known as E3b* and E-M35*).
Before the discovery of SNP/UEP marker M293 in 2008, members of this subclade were indistinguishable from other components within the E1b1b1* paragroup (also known as E3b* and E-M35*), which is a genetic grouping.
