Mutations are important for evolution because they remove excessive genetic variation improve the survival of organisms allow individual organisms to evolve are the source of new genetic variation

are the source of new genetic variation

Explanation:

The concept of mutation is related to the modification of genetic material. Any kind of change, be it in the organization or in number, will result in a new genotype and character.

The importance of mutation lies in the fact that it is precisely that that guarantees the modifications of species, since it is only through a mutation that new genes can emerge. This is why mutations are important and considered the basis for the evolution of species in all populations.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
