Answer:

Yes, because a mutation can help an organism survive in a particular environment.

Mutations refer to the random changes in the genome of the organisms. A mutation can be beneficial, harmful or neutral for an organism. If a mutation imparts certain features to the individuals and helps them to survive under the prevailing surroundings, the mutation is said to be beneficial.
