The BBC recently published an article claiming that "A tiny rodent may have the most sophisticated language of any animal", in reference to the language of a particular species of ground squirrel, the prairie dog. Wow! This is a bold claim, since I was under the impression that humans have the most sophisticated language of any animal.
Anthropocentric views have not disappeared, as is sometimes claimed, but remain embedded in the most innocent of statements. It may seem that prefacing "non-human" to "animal" in the above sentence was unnecessary, but why? One of the shifts in worldview alleged to have been brought about by evolutionary perspectives was precisely the positioning of humanity in the wider context of life - the admission, in effect, that humans are animals. But a great many people do not think this way. They still see 'animal' as a category set apart from 'human'.
