Galapagos Frolic - The Science Show/ABC Radio National

Robyn Williams: The Science Show this week comes from the Galapagos Islands, an hour's flight from the coast of continental Ecuador, it's right on the equator. And I'm here on a personal trip, so no budgets were harmed in the making of this program. And if you saw David Attenborough's magnificent Galapagos series, then this is a follow-up, one that you might do, being escorted by naturalists from Ecuador, as access to these famous islands is strictly controlled.
