Explanation:
Ten thousand years ago was the period in which the last Ice Age ended. The living conditions improved in general across the globe, and this was used by the people in many parts of the world and they experienced rapid developments. Other people groups though didn't really move on and continued to have the same lifestyle, just in a better environment.

It can easily be noticed that in the areas where there were numerous species of animals suitable for domestication and were highly useful, the people were progressing, engaged in farming, and started to have a sedentary lifestyle. On the other hand, in the areas where such animals were lacking, the majority of the people groups remained hunter-gatherers until much later in history.
