Begun last December and scheduled to close two weeks ago, the demanding Charlotte community has persuaded the museum directors to extend its Families of Abraham exhibit. Through photographs and narratives, the popular exhibit shows just how similar we all are. A fact that is thoroughly drummed home when observers are told that at least half the world's people can trace their ancestry back to the father of Ishmael and Issac. Knowledge to live by, I would say. On display through July 31. Mon.-Sat., 10 a.m.-5 p.m.; Sun., 12-5 p.m. $5-$6. Levine Museum of the New South, 200 E. 7th St. 704-333-1887. www.museumofthenewsouth.org.
