List the three places of the world that are the later “haves” in Guns, Germs, and Steel.
I assume that you are asking about Chapter 5 in this question; about some of the "haves" that developed early but were not the first ever "haves." Today, of course, there are many, many "haves" in the world so I assume that you are asking about the earlier times in human history.
If so, you can find your answer in Table 5.1 and in the pages that follow it. Diamond lists 5 places that developed food production on their own (with 4 other places that possibly did so) and he lists 3 places that developed food production after getting "founder crops" from other places. Since you say "the three" later haves, I assume you are asking about the three places that were able to develop food production through "borrowing."
Those places, as listed in Table 5.1, are Western Europe, the Indus Valley, and Egypt. All of these became "haves" when "founder crops" spread to them from the Fertile Crescent.
