I want to know the answer to the following question:
When did Marcin Woźniak search specifically for Slavic sub-group of R1a1a [M17]?
All the background I'm provided with is that "Marcin Woźniak and colleagues (2010) searched for specifically Slavic sub-group of R1a1a [M17].". Is that enough to answer the question?
Answer: yes
