"He explained to me that Humpback Whales sang beautiful songs. They copy from each other, remixing the songs and add to the songs. These songs evolve over time and riffs get passed from whale to whale across the world. The songs have lots of interesting variations and even have rhymes. He made an interesting observation that the whale songs of the 60's were much more beautiful than the whale songs these days." Posted at Joi Ito's Web

So, why are the songs not as beautiful anymore: is the web of life becoming corrupted? Polluted? Singing, after all, reflects our happiness - like when we sing in the shower/bath... I hope our evolutionary shift is not losing it's beautiful song...
