Will mark brainiest and look at the points Mutations can be either spontaneous (no known cause) or induced (caused by specific environmental agents). What are some environmental agents that could increase the rates of genetic mutations among humans today? What types of mutations have the potential to be the most significant from an evolutionary perspective?

Explanation:

Mutations happen spontaneously. The rate of mutation can be increased by environmental factors such as UV radiation , X-rays, gamma rays and certain types of chemicals such as bromine. These are some factor that can increase the rate of mutation

The classic example of evolutionary change in humans is the hemoglobin mutation named HbS that makes red blood cells take on a curved, sickle-like shape. With one copy, it confers resistance to malaria, but with two copies, it causes the illness of sickle-cell anemia. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.
