Human Evolution
I think the stage of evolution that is most important is when our common ancestors gained the ability to adjust to the different climates. Since our world is constantly changing, it is important to be able to survive in different environments. Even now when the seasons change each year, it is important for everyone to be able to adjust to the snow and negative temperatures in winter, as well as adjusting to the heat of the sun that comes in the summer. I also think when our ancestors began to communicate is a very important stage. When each different type was presented to us in the movie, I noticed that little by little, they would start communicating a little bit more. First, we just heard grunts, and then the sounds started to become more and more distinguishable.

These are great facts I also agree on. The ability to adjust and live in different climates is huge, especially moving from Asia to Africa. Many species become extinct due to the fact that they cannot keep up with the changes in the environment. To add, communication could very easily be one of the largest steps. Although it took a long time for it flourish, now the world would not be the same without it. Also, everything has a starting point. We saw here that grunting and panting were the baby steps to universal languages.
