Generations or liters?

[Maliclavelli]

Famous Marko Heinila got drunk: R1b1a2a1a1b3c1a R-M228.2 1 1 4.1 , i.e. R-M228.2 would be 4100 years old, pretty more than R-U152*. That from R1b1a2* to R-L51* could be 11000 years old is possible, it is what I have always supported, i.e. from the Italian Younger Dryas.

See http://beforepresent.dyndns.info/timevalues.html

Giuseppe Belgieri and I know that R-M228.2 is only a few hundreds of years old.

If 4100 years are the interclade between R-M228.2 and R-L196, what does it mean? That these subclades are pretty old how the mother-clade R-U152* (given by Heinila 4200 years old). And why the Italian R-L20 (Belgieri but also Grassi) are the oldest if it is presupposed that at least R-L2, overwhelming in Central Europe rather than in Italy, was born there rather than in North Italy, like the 1000 Genomes data would seem to indicate? Whilst everything is for an Italian origin of R-U152* and the subclades of R-Z36 and R-Z42/Z43. Should we think that Belgieri and Grassi descend from who remained in Italy?

Anyway 1 hundred years to pass from R-U152* to R-L2 to R-L20 seems sincerely a little. More than a bottleneck a coil.
