I want to know the answer to the following question:
When did Boris Arkadievich Malyarchuk use a sample of Czech individuals to determine the frequency of "Monigoloid" "mtDNA lineages"?
All the background I'm provided with is that "Malyarchuk said the "Russian population" was developed by the "assimilation of the indigenous pre-Slavic population of Eastern Europe by true Slavs" with additional "assimilation of Finno-Ugric populations" and "long-lasting" interactions with the populations of "Siberia" and "Central Asia".". Is that enough to answer the question?
Answer: no
