Andrew Wetzler, director of the Endangered Species Project at NRDC, speaks with Daniel Hinerfeld about the misuse of genetic data in determining which animal populations warrant protection under the Endangered Species Act. The Winter issue of OnEarth Magazine has an article by OnEarth contributing editor Sharon Levy called "The Little Mouse that Got in the Way," about a species of jumping mouse nearly doomed by bad genetic science when its western habitat came into the sights of developers. Wetzler also talks about the defeat of Rep. Richard Pombo (R-California), the outgoing chair of the House Resources Committee, who had attempted to dismantle the Endangered Species Act.
