Evolution is driven by a lot of things. It's driven by viruses by definition since of a virus integrates and makes a mutation to the germline, then that's a change which is evolution.

And so so starvation, radiation, chemical mutation, errors in copying, heat, cold, literally everything that impacts survival and procreation drives evolution.
