Carl Zimmer at the New York Times (reg) and his blog, The Loom talks about large scale slicing and dicing of chromosomes and its impact on evolution. Big pieces of chromosome, with the details essentially intact, have been moved around in the interval separating rhesus monkeys from human. Intriguingly, the genes near the evolutionarily defined break points are often associated with congenital disease.
Carl is always worth a careful read.
