State and local dignitaries, students and staff gathered Tuesday on the campus of Georgia Southern University for what President Brooks Keel declared a “truly historic day.” In the morning hours, more than 100 people filled the new 158,000-square-foot Biological Sciences Building on Forest Drive for a ribbon-cutting ceremony to officially christen the science haven. The $41.4 million, state-funded building is home to classrooms, laboratories and offices for faculty and undergraduate and graduate biology students. “(The building) serves as the nexus where teaching and research converge to form south Georgia’s most comprehensive center for biological science and research,” Keel said.
