Web$\begingroup$ Ah, I see. I like how you stated that convergence and divergence are 'really just descriptive terms'- it makes a lot of sense; in any pathway you can probably find a point at which several different inputs can activate a certain protein or have one given effect, or a single protein will have several different effects- divergence.
