At 1 p.m. today I listened by phone to a press conference in Washington where scientists presented the first good look inside a Hobbit’s head. The view is fascinating. While it may help clear up some mysteries, it seems to throw others wide open.

I’ve got an article in today’s New York Times about animal personalities.
In my last post, I traced a debate over the evolution of language. On one side, we have Steven Pinker and his colleagues, who argue that human language is, like the eye, a complex adaptation produced over millions of years through natural selection, favoring communication between hominids. On the other side, we have Noam Chomsky, Tecumseh Fitch, and Marc Hauser, who think scientists should explore some alternative ideas about language, including one hypothesis in which practically all the building blocks of human language were already in place long before our ancestors could speak, having evolved for other functions. In the current issue of Cognition, Pinker and Ray Jackendoff of Brandeis responded to Chomsky, Fitch, and Hauser with a long, detailed counterattack. They worked their way through many features of language, from words to syntax to speech, that they argued show signs of adaptation in humans specifically for language. The idea that almost of all of the language faculty was already in place is, they argue, a weak one.
Earlier this month I wrote two posts about the evolution of the eye, a classic example of complexity in nature. (Parts one and two.) I’d like to write now about another case study in complexity that has fascinated me for some time now, and one that has sparked a fascinating debate that has been playing out for over fifteen years. The subject is language, and how it evolved.
The Sydney Morning Herald reports today that the bones of Homo floresiensis, aka the Hobbits, have at last been returned to the team that originally discovered them.
