I had not heard of this, so yours was an interesting question.
The authors of the paper you gave a link to:
Hardy, K., Brand-Miller, J., Brown, K. D., Thomas, M. G., & Copeland, L. (2015). The importance of dietary carbohydrate in human evolution. The Quarterly review of biology, 90(3), 251-268.
are on ResearchGate; it might be worth contacting them via RG or at their universities?
This paper might be relevant to you; you could also try contacting the authors:
