Full Idea
It is an unwarranted assumption that the only relevant evolutionary period in which our capabilities for emotions evolved is the period in which our ancestors were hunting and gathering.
Gist of Idea
Our capabilities did not all evolve during the hunter gathering period

A Reaction
Goldie says that the evolution of emotions could well extend to much earlier times. Presumably this also applies to other traits, notably those not obviously needed for hunting. Gathering needs long term planning.
