An example of metaphor in popular science writing:
"Despite the enormous diversity of life on Earth, it all belongs to the same evolutionary tree. Species that are close to each other on that tree may look different, because they're suited to dissimilar environments, but they still have underlying features in common. If you say 'animal' to someone, they're most likely to think of a land vertebrate – anything from a frog to an elephant – yet that's really only a small branch of the tree of life…"
