Explanation:
It literally depends on the environments and their surrounding. Also, it can genetic mutations. For example, my friend has greenish hazel eyes while her parents/grandparents don't (btw she's fully asian). This can be due to the environment surrounding her or the cause of genetic mutation. I do feel like genetic mutations are the ones causing us to evolve.
To explain furthermore, the environment can trigger or cause humans to evolve. For example, we all started in Africa, but do you ever wonder how white people became white people? Well, it's because of the cold climate around them. The Africans moved to Europe and stayed there for more than 100 years, and because of that their eyes, skin, lips became lighters.
Lastly, if you have not adapted to the environment around you, there's a good chance mutation and evolving will come along to help humans survive.
