Lugones' "Yzur"

The first-hand account of a scientist who tries to teach his pet chimpanzee to talk. Interesting and not quite as plotless as some of the others. Some questionable evolutionary and linguistic concepts are cited, and it's idea of apes as humans evolved backwards is intriguing. Ultimately, the scientist beats the chimpanzee because he believes the chimp is hiding his ability to speak, with tragic results.
