What is the meaning of 'marshals evidence' in this context:

Most surprising of all to Chua's detractors may be the fact that many elements of her approach are supported by research in psychology and cognitive science. Take, for example, her assertion that American parents go too far in insulating their children from discomfort and distress. Chinese parents, by contrast, she writes, "assume strength, not fragility, and as a result they behave very differently." In the 2008 book A Nation of Wimps, author Hara Estroff Marano, editor-at-large of Psychology Today magazine, marshals evidence that shows Chua is correct. "Research demonstrates that children who are protected from grappling with difficult tasks don't develop what psychologists call 'mastery experiences,' " Marano explains. "Kids who have this well-earned sense of mastery are more optimistic and decisive; they've learned that they're capable of overcoming adversity and achieving goals." Children who have never had to test their abilities, says Marano, grow into "emotionally brittle" young adults who are more vulnerable to anxiety and depression.
'Marshal' = gather and organize.
