Go through any scientific paper and you’ll find it littered with uncertainty. Scientists qualify parameters, give standard errors, make way for random processes even when experiments have been planned to the finest detail. Even when we get the answers we want, we provide alternative explanations that fly in the face of the assumptions we’re trying to test. Honestly, sometimes it seems like we don’t really ‘know’ anything.
I’ve written about our reluctance to declare that we know things in science before, but here I want to try and answer a couple of questions. Why is uncertainty such a crucial part of science? How does this affect the non-scientific public’s perception of science? And does this relationship with knowledge need to change in the future?
When one looks at birds like this puffin, it can be hard to reconcile its cute appearance with its place in the animal kingdom. The thing is, this adorable puffin has something in common with a rattlesnake, in that it’s a reptile (Image credit: Ray Hennessy, Unsplash licence, Image Cropped).
You read that correctly, birds are reptiles. Now, I can hear you saying “but we learned that they are a different group of organisms, and that reptiles are just those scaly animals that have cold blood?” While reptiles don’t have cold blood per se, some of them DO have feathers. And can fly. In this post I hope to convince you of the fact that the puffin pictured above, and all of its avian relatives, belong with the snakes, lizards, crocodiles, and turtles in the reptile group.
Parasites like this leech can be found all over the world, and anyone growing up near freshwater knows to check for them. But many consider these animals “gross”, so how can we motivate the public and scientists to care about them? (Image credit: John Douglas, CC BY-SA 2.0, Image Cropped)
As someone who works with parasites, I have to confess that I love them. They are beyond interesting, and I delight in telling people about them and what they do to their host organisms to survive. More often than not, people cringe or look like they would rather run away than hear more about such disgusting creatures. I know that as a disease ecologist I am very much in the minority when it comes to how I feel about parasites, but I think it’s important that we understand how vital these organisms are to the natural world, and the benefits they offer to scientists and their research.
