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.
The individual Quokka isn't making that analysis, but evolutionary selection is
Evolution doesn't work that way. It's not picking and choosing traits. It's not making analysis.
The quokka just survives to pass on that trait so it persists.
Semantics, but I would say evolution is indeed picking and choosing traits, in the sense that an algorithm picks a result. It's not some conscious being though.
semantics are important when talking about evolutionary science. especially when a large segment of the population dismisses evolution as a "theory" with little understanding of what the term "theory" means in the context of science.
Gravity is also just a "theory", that's why I float off into space some days.
yes 👍
