Can mongoose pups conceal their identity?
Mongooses live in cooperative groups where the adults work together to help raise the pups. You'd assume that if a mongoose knows which pups are his or her own, that they'd tend to try and help them out more if possible, but a new study shows quite the opposite - adult mongooses dole out their assistance at random with respect to relatedness, suggesting that they may not be able to tell the difference after all. This might be crucial to protect mongoose pups from aggression from unrelated adults.
