Can't Miss It: Tuesday

BEACHES: If you visit the Seattle Aquarium tonight, you can sign up to be a volunteer Beach Naturalist this summer. What is a Beach Naturalist, you ask? You get training, and then spend three or more summer days educating visitors about beach ecology and beach etiquette. Sites include Des Moines, Seahurst Park, Lincoln Park, South Alki Beach, Golden Gardens, Carkeek Park, and Richmond Beach. They prefer if you live near a beach, but they also seem kind of desperate so may take you if you're breathing.

7:30 p.m. // Seattle Aquarium, 2nd Floor // FREE, but RSVP

SCIENCE: In his talk "Organism and Environment: The Organism as Subject and Object of Evolution," Richard Lewontin, evolutionary biologist, geneticist, and social commentator, has a few corrections to Darwin's thought to share. It is now clear, he argues, that all organisms actively create and alter the environments in which they live, so that every internal physical change induces a change in the corresponding environment. Evolution, then, is co-evolution. Big difference.

FILM: At this installment of Exposed: Inside Film, The Golden Compass is going to be shown, and then there'll be a conversation with writer and director Chris Weitz. Warren Etheredge has the unenviable task of asking Weitz how he missed the point of a single film so widely, when he had a perfectly good novel to draw from. Weitz also directed American Pie and About A Boy, so maybe he should stick to films that begin with A.

7 p.m. // EMP, JBL Theater, 325 5th Avenue North // Tickets: $5 [SOLD OUT, but you can get on the wait list by calling 206-770-2702]
