A bodily disposition whose realization ordinarily brings benefits to an organism or group of organisms, where "ordinarily" means within a typical range or context.
The phrase 'ordinarily brings benefits to an organism or group of organism' is used to explain that capabilities normally provide a benefit. For instance, having a musical ability is ordinarily an ability that is positive for a person (e.g., they receive positive feedback about their ability). However, in certain exceptional cases (e.g., a neighbour becoming annoyed with a person playing the piano and expressing this annoyance), the ability might not bring benefits.
