Does Chomsky Die in the Amazon?

Thanks to a user's comment on a review on AV Club, I spent the past hour reading a fascinating article about a possible refutation of Chomsky's Universal Grammar.  The article is quite long, but in short, a linguist and his wife, Dan and Keren Everet, went into the jungles of the Amazon to convert the Pirahã to Christianity by translating the Bible into their language.  The Pirahã language is notoriously challenging to outsiders, in part because it relies heavily on parsody and seemingly lacks color terms, numbers, abstractions, and recursion.  The work, over a couple of decades, drove Dan from his faith and split the couple.  Dan's research challenges Chomsky's belief that recursion is a universal language trait.  Since Chomsky began formulating his theory - which is now akin to dogma in linguistics - he has refined his belief in recursion to the point where it is the core tenet of what makes human language unique among living beings.  If a tribe in the Amazon lacks recursion, does that lend credence to older theories like Sapir and Whorf's? 
Very good read.
