How do you explain similar habitats on other continents?

What similar? The American Prairie is unique in the world.

I think he was referring to the pampas of Argentina, the savannah of Africa,
the steppes of Russia, maybe other similar that I'm forgetting. He said
similar, not identical. They're all places naturally devoid of trees.
