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