Was Jared Diamond on track with his theory of "geographic luck"?

The way that I see it is that Jared Diamond was on track with his theory of geographic luck. I think this because he has all of the right details about what makes and what doesn't make a place geographically lucky. He was right when he said that it takes different types of animals and plants to actually have a successful place to live. Back when these people were living you would also need the right climates for the people to live in and for the plants and animals to actually survive. He also stated about the different in technology and civilizations. But mostly his theory revolved around the climates because not everything can survive and grow in cold climates you might need a warmer climate to not only live but grow animals and plants. That is also why people have migrated over centuries. The roles that the people have had in the communities were very important to the villages and you could never slack because they needed this stuff to survive.. Some of the roles the men and women were equal and some of them weren't  The men would usually go out in hunt, in the period when the men were doing that the women would gather and plant the food that they would need to survive. As the time progressed and the people started to actually settle down and stay where they were because the realized that they could actually have a living there. This started to lead to the many inventions that people were creating so it would be easier for them to live and the people around them to live. This is what can support his theory on why the people the Europe founded and had guns, germs, and steel in there area.
