What Would Falsify the Explanation?

I hesitate to say something's falsified if I don't have a rival theory, a rival explanation. So I was wondering what would falsify the explanation we just laid out with the like flowers and insects and things like that. If other animals were also attracted to flowers, without a coefficient of history with flowers like insects. That would, for example, be that would falsifying the theory know I don't know of any animals but I'm imagining so yes yes that that would.
