The Plan To Bring The Passenger Pigeon Back From Extinction

The Passenger Pigeon is an extinct North American bird. The species lived in enormous migratory flocks until the early 20th century, when hunting and habitat destruction led to its demise. One flock in 1866 in southern Ontario was described as being 1 mile wide and 300 miles long, took 14 hours to pass, and held in excess of 3.5 billion birds.

Last week scientists met in Washington, D.C. to discuss a plan to bring the passenger pigeon back from extinction. 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.
