Hand a kitchen appliance to a child and they’re likely to find a whole new way to use it. This happens in evolution, too – traits adapted for one purpose turn out to be beneficial for a whole other reason, and so the trajectory of natural selection changes.

Let’s discuss what this word means, why it exists, and what some people find wrong with it.
In the news: the oldest forest, an ancient parent, young T. rex, and fossil lungfish.
