A Tuesday presentation featuring famed naturalist Dr. Edward O. Wilson and author Tony Hiss has been cancelled.



"Dr. Wilson has incurred a medical urgency this morning that prevents him from presenting at the scheduled event," said Christy Scally, of the E.O. Wilson Biophilia Center.  "Dr. Wilson is hospitalized, doing well and expected to make a full recovery."



The pair was set to speak April 2 at Freeport High School and organizers were expecting hundreds to attend.



 "We are sorry for any inconvenience," Scally said. "And our prayers for a full recovery are with Dr. Wilson and his family."
