For example, Professor Diamond touches on the subject that some people groups were eager to accept ideas and inventions that were introduced to them, whereas others simply ignore the same ideas and inventions and stuck to their traditional ways. I believe that humans are uniquely created with individual personalities. Thus, even given the same set of circumstances or the same set of materials, individuals or groups of individuals would not necessarily interact and respond the same way as each other or as the original groups historically have responded. Even today, people adapt differently from each other when put in the same set of circumstances or the same environment. Some people accept technology and new ideas better than others.
Some people prefer to stay with tradition.
Environmental factors can go a long way to explain how things have happened, but the environment alone cannot help us understand why humans approach things the way that we approach them. To throw out history, sociology, or other ways of study and try to base the explanation of why these events occurred the way they did using only environmental factors is a mistake, as it cannot give us a complete understanding of how and why we as humans operate and react the way we do. We are impacted by more than just our environment. It is an important factor, but not the only factor in our formation as individuals and in the development of societies.
