I want to know the answer to the following question:
Did Eran Elhaik, from Johns Hopkins University School of Public Health argue for or against Khazar descent?
All the background I'm provided with is that "In late 2012 Eran Elhaik, a research associate studying genetics at the Johns Hopkins University School of Public Health, argued for Khazar descent in his paper". Is that enough to answer the question?
Answer: yes
