Last night we watched a National Geographic documentary on Madagascar. It opened with the narrator saying “some bajillion years ago, Madagascar broke away from the coast of Africa.” Of course, he didn’t say bajillion, but I can’t remember the actual number.
I’m confused by this concept of breaking away. It’s not as if islands float, they’re attached at the bottom, right? The little graphic in the documentary made it look as if a small chunk of land drifted off, sort of like a piece of ice breaking off of an iceberg, and floated away. How exactly would this work? Did it happen all at once, like a big earthquake, or was it a gradual process?
Next, the documentary moved on to lemurs. And boy, are they cute. Lemurs are primates. However, several times, the narrator referred to a common lemur ancestor, and described it as “squirrel-like.” Now I know that National Geographic is the ultimate for putting scientific things in layman’s terms, but is there any scientific reason AT ALL that lemurs would be like a squirrel? Or was the program simply trying to create an image of a small furry thing that scampers around in trees?
