Not deeper than a surface level understanding of evolutionary biology, no. Apparently nobody knew how sweetness works until 2001 when researchers found the specific protein that detects sweetness, and then 2012 when the receptors for that protein were figured out. Just think about that. Until ten years ago, nobody even knew how sweetness works, yet artificial sweeteners have been in use for 50.
