Which is correct, no-mans-land or no-man's-land? I think the latter is, but the text gives it otherwise.
One reason that so many of us are fascinated by penguins is that they resemble us. They walk upright, the way we do, and, like us, they are notoriously curious creatures. Penguins in the wild walk right up to people, touch them, and look as if they were preparing to study them. Diane Ackerman points out that "there is, ordinarily, a no-mans-land between us and wild animals. They fear us and shy away. But penguins are among the very few animals on earth that cross that divide. They seem to regard us as penguins, too, perhaps of a freakish species. After all, we stand upright, travel in groups, talk all the time, sort of waddle." Bernard Stonehouse, the worlds leading authority on penguins, believes that they think a human is a penguin who is "different, less predictable, occasionally violent, but tolerable company when he sits still and minds his own business."
