, have a test on wednesday!

Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.

Explanation:

As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well. For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.
