The Surprising Brain Chemistry That Turns Ants Into Caregivers

A study in clonal raider ants found that two neuropeptides help switch workers between caring for larvae and foraging.

The molecules, neuropeptide F and Allatostatin A, are tied to ancient hunger-related circuits.

The results suggest caregiving and other social behaviors can evolve by repurposing older brain pathways.

The findings from Rockefeller University were published in Nature.
