1. 1

    A mutation is a change in the genetic instructions (DNA) inside a living thing's cells. Mutations happen naturally all the time, usually with no visible effect, but sometimes they cause a new trait to appear — and if that trait gets passed to children, it can change a whole species over a long time. Outside of science, people sometimes use 'mutation' loosely for any strange, unexpected change.

A good example is mutations that disrupt seed dispersal, leaving the seeds on the heads long after they are ripe.
