📣 Super cool new study on the *evolution of helping* by Kirstin Gaffney open access in @behavecol.bsky.social academic.oup.com/beheco/artic...

Pay-to-stay drives the evolution of helping independent of kin selection in anemonefish societies

We found evidence for “pay-to-stay” in anemonefishes (gaining future benefits from current cooperation at their own expense). This confirms that helping ca
