Guns, Germs, and Steel chapter two question

What role did ‘geography’ play in the story of the Maori and the Moriori?

both group were Polynesian and were Maori. After the Maori had populated the Chatham islands they became the Moriori. After a few centuries the two groups became different types of people. The Maori on the North island developed more complex technology than the Moriori. The Moriori became hunter- gatherers and the Maori became farmers. This is what led to their fighting. Also different environment affected the way each groups lived and survived.
