Do Quokkas Actually Throw Their Babies At Predators?

This question started as an online joke, and as time went on, people started taking it seriously. The answer to the question isn’t that simple, however. Firstly, it should be noted that no, quokkas don’t throw their babies at predators. That is a joke, but it is somewhat based on reality. Quokkas keep their young in their pouches, and while fleeing from predators, babies are known to fall out and are then left there by their parents.

The thing that is interesting here is that the part where they fall out of the pouch may be done on purpose by the mothers. Research shows that this may be an actual anti-predator characteristic of quokkas. They normally have very strong control over the muscles in their pouches, so their response to the threat of predators may be to release those muscles. The babies are left there to attract the attention of the predator, and the parents can safely escape. Mothers want to save themselves because they have proven that they are fertile, while the young might not be.

but that's an analysis a human scientist is making. not the quokka

This is an important distinction to make in general regarding science communication about evolution. Far too often, the evolutionary process is anthropomorphized, adding confusion to the scientifically illiterate. I watched a documentary once where some biologists were in the Amazon, noticed a brightly colored fish, and opined to the camera "why would evolution do this?" That is a terrible way to communicate a scientific curiosity.
