 More recently, geneticists have attempted to make precise the notion of a group adaptation though the “Formal Darwinism Project” (Grafen 2008), in which the general concept of adaptation can be applied to groups (Gardner &amp; Grafen 2009). However, it is unclear how the notion of adaptation developed within the formal Darwinism project relates to the previously discussed engineering notion of adaptation. Philosophers have offered a different analysis of group adaptation, one based on an earlier analysis of selection and adaptation (Okasha &amp; Paternotte 2012; Grafen 2008). The key distinction, in the original view, is between a trait that is a trait that merely benefits the group, i.e., “fortuitous group benefit,” and one that is a genuine group adaptation, a feature evolved because it benefited the group, i.e., “for the right reason” (Okasha &amp; Paternotte 2012: 1137). Contextual analysis, as well as the Price equation, can provide a formal definition of group adaptation, but both need to be supplemented by causal reasoning (Okasha &amp; Paternoster 2012).
