Explanation:
Evolution may be defined as any net directional change or any cumulative change in the characteristics of organisms or populations over many generations—in other words, descent with modification state. It explicitly includes the origin as well as the spread of alleles, variants, trait values, or character states.
The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today. Then about 13.8 billion years ago, space expanded very quickly (thus the name "Big Bang"). This started the formation of atoms, which eventually led to the formation of stars and galaxies.
