Observability/Fraassen: e.g. Darwin's missing link: was an observable entity! - e.g. elementary particles: brought their own properties.

Observability/Fraassen: there is no logical link between observability and existence. A theory as far as empirical adequacy is concerned would be just as good if nothing existed that is either unobservable or non-actual.
