I want to know the answer to the following question:
Researchers from which university challenged the theory of race being only a social construct?
All the background I'm provided with is that "The theory that race is merely a social construct has been challenged by the findings of researchers at the Stanford University School of Medicine, published in the American Journal of Human Genetics as "Genetic Structure, Self-Identified Race/Ethnicity, and Confounding in Case-Control Association Studies".". Is that enough to answer the question?
Answer: yes
