Evolution happens over a very long period of time, our earliest ancestor was recorded to have evolved almost 2 million years ago. And during that time, natural selection played its role in shaping up (and weeding out) our ancestors and it led to us, humans.
Heredity, on the other hand, refers to the passing of characteristics from one generation to another. This can include facial features, body characteristics, and even genes for congenital disorders.
