One might get some idea if the eyebrow was evolving due to some usefulness by looking at various isolated tribes living with different cultures and within ecosystems/climates (would be much easier to do if one had a time machine). I tend to agree with you that a lot of things that are called "science" are mainly story telling. There is "physics envy" for a reason. Physics focuses on a very small subset of reality that have observations that are true with uncertainties of 5, 6, 9 sigmas. This is the level of truth one needs to build up a models of complex things that match reality almost all the time. Physicists at LIGO or CERN don't publish in journals some observation with P=0.05 and expect others to use it. Hopefully the reproducibility crisis in psychology will get many truth seeking fields to spend more time on understanding what is true at the lowest level. Feynman had a good essay about this issue many years ago about rat studies[1,2].
