Taken together, this body of work is consistent with the conclusion that elevated avuncularity by androphilic males is an adaptation that evolved via kin selection.
In addition, data from contemporary transgendered male androphiles (fa'afafine) indicates that they exhibit elevated avuncularity.
In such a situation, increased avuncularity among male androphiles could potentially facilitate reproduction by female kin and thereby have positive "effects" on the genetic factors for both increased fecundity in females and, by extension, its conjectured by-product, male androphilia.
If so, then the cognitive underpinnings mediating avuncularity in male androphiles may have subsequently undergone secondary adaptive modification.

Relationship status and elevated avuncularity in Samoan fa'afafine.
Consequently, Vasey suggests "that the fa'afafine's avuncularity
probably contributes to the evolutionary survival of genes for male same-sex sexual attraction, but is unlikely to entirely offset the costs of not reproducing.
Principled, socially conscious, modest, and with a mischievous sense of humor is how he emerges, with a sort of likable avuncularity
that one would always wish for in one's literary heroes.
Now, I understand that even though no human being can be that genuinely excited about the weather, this sort of avuncularity
is expected out of weather reporters.
