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.

    Maybe their flight response causes them to lose control of their pouch muscles (because that’s not a priority to survive), therefore accidentally dropping their babies.

      While this may have happened accidentally at times, there is no way the potential for an accident like that would not be either selected and incorporated, or selected against and rejected as a survival trait.

        Not necessarily. Evolution doesn’t optimize trait by trait.

        If the flight response leads to overall more reproduction it would naturally pass on regardless of any effect of the loss of pouch control.

        The dropping of the baby wouldn’t necessarily be a trait itself, but a side effect of the flight response.
