I want to know the answer to the following question:
What haplogroup did a DNA analysis of the Liangzhu culture reveal?
All the background I'm provided with is that "A 2007 analysis of the DNA recovered from human remains in the archeological sites of prehistoric peoples along the Yangtze River shows high frequencies of haplogroup O1 in the Liangzhu culture, linking them to Austronesian and Tai-Kadai peoples.". Is that enough to answer the question?
Answer: yes
