"Problem solving in low-ranking individuals in animal groups" (Charles Darwin as the first anti-psychiatric thinker timeline)

In the Charles Darwin as the first anti-psychiatric thinker timeline, "Problem solving in low-ranking individuals in animal groups" was a book written by Sandra Tanner in 1839. In the book it is noted, citing Charles Darwin's naturalist notes from the HMS Beagle expedition, that in hierarchical animal groups, the lowest ranked individuals always need to be the best problem solvers. It is concluded that the notion of women being naturally less good at technology and engineering than men is incompatible with the notion of natural male dominance. This makes the book one of the most important works for early feminists.
