But GG&S continue to falls into the exact same category of theories that try to cut back complex history to only one easy issue. Although It appears apparent that any continent achieving food items production earlier than others is a vital Think about turning into dominant (especially concerning distant continents), this does not get rid of prospective other things also currently being concerned.
In other words Except With this case, in opposition to Jared Diamond claims, it wasn't currently being lucky in acquiring awesome animal, but millennia of domestication.
The geographical boundaries described by Diamond are possibly not as sound as one could suppose or weren't genuine the past:
