Common Trait, Not a Common Ancestor

It is something we say a lot as Creationists, but here it is an Evolutionist that says it:

But as similar as their characteristics are, trees aren't all related to each other. They're just a habit, or a form that a plant can take. You can find trees all over the evolutionary map.

"There are lots of [plant] families that are only herbaceous," Kimmerer said. "There are even more families that have both herbaceous and tree members. And then there are a few families that are only trees."
