I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The last three chapters have been about genetics, and I'm not a fan of the way the authors write about ants as though they're aware of their genetic makeup and are purposely aiming to support the continuation of their genes over the genes of less related ants in the same colony. There's been one mention that their actions are probably based on scents, which have a genetic basis, rather than an actual awareness of each others' genes, but it mostly isn't written that way.
Also, these chapters are a bit confusing. And parts of them contradict other parts and make me wish this were a classroom and not a book, so that I could raise my hand and ask questions.
