Convergence or divergence? (Introduction)

Echolocating is found in bats; I've heard their sonar on the Grand Canyon trips. Dolphins use it also. This is a prime example of convergence, and it requires over 200 changes in DNA to get there:-"To search for genes that evolved convergently in echolocating animals, the researchers lined up the genomes of 22 mammalian species, only some of which echolocate. The species included the bottlenose dolphin and four bat species whose genomes the researchers sequenced for the study: three bats that echolocate and one that doesn't. The researchers then used a computer simulation to scroll through the genomes and correlate mutations with ability to echolocate. The researchers report September 4 in Nature that nearly 200 genetic regions stood out as evolving together ... far more than the researchers had expected. -"This highly specialized life trait is affecting vast portions of the genetic makeup of the organism, not just one or two genes," Parker says.
