I2a2a-Disles (Dinaric-type in Britain): 2985 BP (1000 BCE)
as the signal close in time to the proto-Celtic ethnogenesis:

Herodotus thought the Cimmerians and the Thracians closely related, writing that both peoples originally inhabited the northern shore of the Black Sea, and both were displaced about 700 BC, by invaders from the east. Whereas the Cimmerians would have departed this ancestral homeland by heading west and south across the Caucasus, the Thracians migrated southwest into the Balkans, where they established a successful and long-lived culture. The Tauri, the original inhabitants of Crimea, are sometimes identified as a people related to the Cimmerians and later the Taurisci.
 
It looks like they're using FTDNA nomenclature. It's a bit dated (2010), so there are some wrong conclusions here that we understand better now, such as:

all I2* today living (Caucasus): 5574 BP (3600 BCE)

Under FTDNA nomenclature, all L596+ ("I2c") and L416+ ("ADR") is I2*, and L596+ and L416+ are far enough from each other that 5574 YBP is very much too young, not to mention that L596+ is not most diverse in the Caucasus (in fact only one of its two major branches is even found there) and L416+ isn't found in the Caucasus at all.

I2b ancestor (I2b1 vs. I2b2 separation): 8822 BP (6800 BCE) - note: First farming sites in Thessaly, Greece: 6500 BCE

Also seems too young, not to mention weirdly precise. Greece is surely too far east unless we're going by a "total displacement" model.

I2a ancestor (P37.2+): 10.366 BP (8400 BCE)

Way too young.

I2a (xI2a1): 8535 BP (6500 BCE) - Carcium Pottery Neolithic in the Mediterranean from around 5700 BCE

Too young, and the conclusion doesn't make any sense. All of the M26- clades are clearly more diverse north of the Mediterranean... even the French outliers veer away from Southern France.

I2a2b (L161) - Isles: 6803 BP (4800 BCE) - Britain - note: Early Neolithic in Britain (Long Barrows) from 4400 BCE

This one is now usually recognized as more diverse on the continent than in Britain, although it's an interesting subject still worth exploring.
