Nathaniel Rich’s article on the de-extinction movement includes this letter by Stewart Brand to George Church and Edward O. Wilson:

Dear Ed and George . . .

The death of the last passenger pigeon in 1914 was an event that broke the public’s heart and persuaded everyone that extinction is the core of humanity’s relation with nature.

George, could we bring the bird back through genetic techniques? I recall chatting with Ed in front of a stuffed passenger pigeon at the Comparative Zoology Museum [at Harvard, where Wilson is a faculty emeritus], and I know of other stuffed birds at the Smithsonian and in Toronto, presumably replete with the requisite genes. Surely it would be easier than reviving the woolly mammoth, which you have espoused.

The environmental and conservation movements have mired themselves in a tragic view of life. The return of the passenger pigeon could shake them out of it — and invite them to embrace prudent biotechnology as a Green tool instead of menace in this century. . . . I would gladly set up a nonprofit to fund the passenger pigeon revival. . . .

The details of how it de-extinction would actually work are fascinating, and if you stick with the article long enough, it does include some criticism from mainstream biologists. For one thing, this isn’t really bringing back an old species so much as it easy creating a new species that is very close to the old. In fact, one environmental lawyer has already suggested that such species could be patentable.

(Thanks Bill!)
