Answer:
Yes
Step-by-step explanation:
Environmental factors caused many different traits in people, for instance the different skin pigments of people depend on where their ancestors came from. European descendents tend to absorb more sunlight and get sunburned easily, whereas African descendents have skin that is suitable for their environment. Other characteristics include immunity to malaria or the speed at which one's blood can carry oxygen. These traits came slowly through natural selection as people evolved to become suited for their environment.
