Kazakh ancient N-haplogroups were N1a1a1a1a

 Several samples from the time around 300 BC in Kazakhstan belong to the same haplogroup level than Kola Peninsula samples from 1500 BC, reported by mutations L1026 or L392.  I was not able to find any RECENT ISOGG downstream mutations, which makes me think if all European side N can be derived from these Kazakh Iron Age men.  If this is true we have a problem with the home land of Finnic speakers, considering that they belonged to N and home  land of them was not near Kazakhstan.   At 500 BC we should find downstream mutation taking into account datings of the first Finnic speakers in the Baltic area and believing in the incidence of N1a1a1a1a at 500 BC in Europe and in Central Asia simultaneously.  TMRCA of the N1a1a1a1a is according to Yfull 3000 years (1000 BC).  The mystery of the origin of European N remains.   Everything proves about a rapid expansion to the Baltic area and to North Russia.  What ever caused this, what language they spoke and adapted remains without answer and makes the mystery even deeper after these finds from Kazakhstan.  Another explanation is that there was still unknown brance of N1a1a1a1a somewhere in West Siberia or Northern Russia around 1000-500 BC, but we have not evidence of it.
