I want to know the answer to the following question:
The founder lineages were likely from what type of mtDNA pool?
All the background I'm provided with is that "In reference specifically to Haplogroup K, they suggested that although it is common throughout western Eurasia, "the observed global pattern of distribution renders very unlikely the possibility that the four aforementioned founder lineages entered the Ashkenazi mtDNA pool via gene flow from a European host population".". Is that enough to answer the question?
Answer: no
