Interesting question, I did some searching. I guessed they might have done such research with fruit flies [1], but I can only find one plan to try it for nine generations [2]. I suspect that project never launched because of the end of the space shuttle program. I can’t find a relevant paper by the mentioned researchers in any case. All the other Drosophila research seems limited to a single generation in space. (It seems like C. Elegans has not been studied in space to the same extent as fruit flies.)
