Poo turns naked mole rats into better babysitters

Mole rats are very sociable weird animals, and one of the reasons they are so weird is that they eat one another’s, and their own, faeces. But this isn’t done just for fun; scientists have found a biological motivation for this behaviour. Like bees, naked mole rats live in eusocial colonies, with only one queen rat and a few males that can reproduce. The rest of the colony consists of dozens of infertile, sexually immature – so don’t produce hormones - subordinates that help with tasks such as foraging, taking care of the pups and defending the nest. The Oestrogen in queen mole rat’s faeces drives her subordinates to care for her pups. The boost in female hormone from the queen’s faeces activates their maternal behaviour.
