Past Event

TEDxDeExtinction in Washington, D.C.
Join the first-ever public exploration of the subject of reviving extinct species.

Registration: 7:30–8:30 a.m.
Conference: 8:30 a.m.-5 p.m.
Reception: 5–6 p.m.

In this decade some extinct species will begin to come back. Rapid advances in molecular biology are converging with new perspectives in conservation biology to create a new field called “de-extinction.” Now is the time to begin public discussion of how de-extinction projects can best proceed responsibly.

On Friday, March 15, National Geographic is hosting the first-ever public exploration of the subject of reviving extinct species at TEDxDeExtinction, a daylong event at Grosvenor Auditorium in Washington, DC.

Applicable genetic technology breakthroughs are coming almost monthly these days. We will hear from leading practitioners such as George Church (Wyss Institute, Harvard), Robert Lanza (Advanced Cell Technology), Michael McGrew (Roslin Institute), Beth Shapiro (UC Santa Cruz), and Oliver Ryder (The Frozen Zoo, San Diego Zoo).

There will be reports on species-revival projects under way—European aurochs (Henri Kerkdijk-Otten); Pyrenean ibex (Alberto Fernández-Arias); passenger pigeon (Ben Novak); American chestnut (William Powell); Tasmanian Tiger and another iconic extinct Australian animal (Michael Archer); California condor (Michael Mace); and the woolly mammoth (Hendrik Poinar).

The goal of ultimately restoring revived species to the wild brings up important ethical and practical issues. The conservation perspective on de-extinction will be represented by Kate Jones (IUCN-Red List), Stanley Temple (University of Wisconsin; a founder of conservation biology), Kent Redford (former head of Conservation Strategies at the Wildlife Conservation Society), David Burney (Conservation Paleobiology, Kauai), and David Ehrenfeld (Rutgers; founding editor of Conservation Biology).

NOTE: Please confirm you can attend before processing your registration as all sales are final. See our Ticket Policies and Procedures.
