Other forms: mutated, mutating, mutates
To mutate is to change form, especially in living things. The virus mutated, mutated genes, mutate over time.
Most mutations do nothing at all, a few are harmful and very few are useful, and that last group is what natural selection works on. Viruses mutate fastest because their copying is sloppy, which is why influenza vaccines are reformulated yearly. Note mutation; and that the Latin means to change, the same root as moult.
