> as the parent comment points out, lots of issues have been found with it.

I'm not familiar with the research here so I can't say either way. But a preliminary google scholar search turned up a lot of articles which seem to suggest that breastfeeding has a bunch of positive impacts on numerous intelligence and general well-being metrics.

The article itself has been cited 209 times according to google scholar [1], and this study [2] (cited 400+ some odd times) seems to accept some of the propositions made in this paper as givens.

Anyway, I think it would have been interesting if the null hypotheses here weren't rejected. I kind of expect evolution to have optimized human breastmilk over alternatives for infant development.
