And counting...
The definition of a Lineage in the Sinclair DNA study has changed quite a bit since we started back in 2004. If you're participating in an active DNA study, it's important to understand just how dynamic they are. As new distinctions come along, a good administrator will give the different groups unique names. Early on, we grouped people by numbers - Lineage 1, Lineage 2, etc. This was based in part on how old their genealogy was. Then we switched to early SNPs like R1b. Those who follow DNA studies know that this is now ridiculously broad. But back then we were working with the data we had. As time has gone by, the R1b group has split up into over 8 Lineages.
Even those Lineages we divided up have had to be further segregated. We've still got some people calling lineages by the names we used in 2004. One group was called Lineage 4. It's changed because SNP studies have proven that the members within Lineage 4 split into 4 groups who don't share a common ancestor for about 2,300 years (based on the current accepted calculations).
