Carol Flanagan passed along a link to a Wired.com  article about a plan to bring the Passenger Pigeon back from extinction.

Here's a sample:  "The technical challenges are immense, and the ethical questions are slippery. But as genetic technology races ahead, a scenario that’s hard to imagine is becoming harder to dismiss out of hand.

"About 1,500 passenger pigeons inhabit museum collections. They are all that’s left of a species once perceived as a limitless resource. The birds were shipped in boxcars by the tons, sold as meat for 31 cents per dozen, and plucked for mattress feathers.

"But in a mere 25 years, the population shrank from billions to thousands as commercial hunters decimated nesting flocks. Martha, the last living bird, took her place under museum glass in 1914."
