I want to know the answer to the following question:
Who used a sample of Czech individuals to determine the frequency of "Monigoloid" "mtDNA lineages"?
All the background I'm provided with is that "In 2008, biochemist Boris Arkadievich Malyarchuk (Russian: Борис Аркадьевич Малярчук) et al. of the Institute of Biological Problems of the North, Russian Academy of Sciences, Magadan, Russia, used a sample (n=279) of Czech individuals to determine the frequency of "Mongoloid" "mtDNA lineages".". Is that enough to answer the question?
Answer: yes
