Proceedings of the Royal Society B: Biological Sciences, 284(1854), 20162384. https://doi.org/10.1098/rspb.2016.2384

Kin selection theory predicts that animals should direct costly care where inclusive fitness gains are highest. Individuals may achieve this by directing care at closer relatives, yet evidence for such discrimination in vertebrates is equivocal. We i...
