Ok, here again about the haplogroup N, which is closest related to O, a clearly Mongoloid East-South East Asian haplogroup.
At that time we deal with AT LEAST Europoid forms in West Eurasia!
http://en.wikipedia.org/wiki/Haplogroup_N_(Y-DNA)
At that time progressive Europids, especially more and more leptodolichomorphic variants from the South and East, expanded in Europe.
If that timeline is even remotely correct, an Europid origin of N is totally out of question and that even Baltic Finns deviate, at least somewhat, with their autosomal DNA towards the East Asian populations in comparison to the rest of Europe points also to the same pattern.
At that time you deal with the first Neolithic populations and Europe being dominated by clearly Europid variants already - when the carriers of N finally make it into the continent.

The N carriers might have been no classic Mongolids, but more Mongoloid than Europid and clearly different from both the archaic Cromagnoids in the North East, as well as the more progressive Cromagnoids and Aurignacoids further South.
The racial-phenotypical impact was very limited but being most evident in Europe's racial variation among Lappids (core group) and Eastbaltids (distinguished from Baltised Cromagnoids = Westbaltid-Baltid by their Mongoliform/part Mongoloid characteristics).
