An interesting article appears today in the
San Francisco Chronicle about debate at UC-Berkeley over the cause of the extinction of the dinosaurs. Was it caused by a comet striking the Earth? Or something else? A more precise estimate of the timing of the strike has been produced.
But what happened to the Disney hypothesis - which Southern Californians can relate to - that it was all due to too much sunshine and not enough water?
Anyway, you can read the article at:
