Very recent - Evolutionary processes seem also now to exclude men entirely from becoming teachers, something which whilst never “Gender neutral” did used to have a reasonable number of very good male teachers of passion and ability (amongst the “chaff”).
Yes I agree, “Nurture” is at least as important as “Nature” in the production of the person, But that also brings on questions of policy and “improvement” in policies towards the population as a whole, which must not be discussed here except possibly in PMs.
Good and thoughtful post
