Daily Times Web site._”With some major exceptions, there’s been a 20-year retraction” in museum-based natural history research, said Leonard Krishtalka, who directs the museum at the University of Kansas. “We’re slowly witnessing, by the whittling of curatorial positions, the extinction of incredible knowledge.
