What would happen if we didn't have mutations?

Answer 1

Life would've probably gone extinct ever since it's beginnings, and if it didn't that would've been either luck or a high level of reproduction throughout the species.

Answer 2

Without mutations, there would be no genetic variation, making evolution impossible. Mutations are essential for introducing new traits and diversity in populations, which allows for natural selection to act upon. Therefore, without mutations, species would not be able to adapt to changing environments and would likely become extinct.

Answer 3

Mutations can be seen as good or bad. Without mutations each species would cease to evolve- or adapt- and would die off.
