What the article says around this equation
The same mark-recapture and genetic-sampling infrastructure that estimates is what field studies of adaptation and cooperation are built on. Heritable variation in a trait under selection — the beak-depth story above — requires knowing which individuals are related to which, which in turn requires either pedigree reconstruction from genetic markers or long-term individual-based mark-recapture records linking parents to offspring across seasons. Studies of cooperative behavior (helpers at the nest, alarm calling, reciprocal grooming) that invoke kin selection as an explanation are only as strong as the relatedness estimates behind them, and those relatedness estimates come from the same…

Heritable variation in a trait under selection — the beak-depth story above — requires knowing which individuals are related to which, which in turn requires either pedigree reconstruction from genetic markers or long-term individual-based mark-recapture records linking parents to offspring across seasons. Studies of cooperative behavior (helpers at the nest, alarm calling, reciprocal grooming) that invoke kin selection as an explanation are only as strong as the relatedness estimates behind them, and those relatedness estimates come from the same genotyping pipeline described in workflow two, just applied pairwise between individuals rather than population-wide.
