The topic of human evolution will take the stage starting Thursday as Summer Youth Theatre performs “Inherit the Wind,” a play based on the 1925 Scopes monkey trial. A cast of 25 students, in eighth through 12th grades, are staging the production as part of the annual program at the Lawrence Arts Center. The play, by Jerome Robbins and Robert E. Lee, is being directed by Chris Roady. The show runs at 7:30 p.m. Thursday, Friday and Saturday, with a 2 p.m. matinee on Sunday, all at the arts center, 940 N.H.
