        Potential to Revive Extinct Animals Raises Ethical Questions

        Researchers are working to bring back extinct animals, like the woolly mammoth and passenger pigeon, operating under the belief that reviving such species could restore vanishing habitats. However, many biologists suggest these efforts should focus on endangered, rather than extinct, species. For further background and materials to support student understanding of the issue see the Teacher’s Guide, Student Handout, and Informational Text in Support Materials.
