AMC has suggested that the zombie variants in The Walking Dead: Daryl Dixon may have been manmade. The series premiere reveals the existence of a new type of zombie called Burners in France. A post-credits scene from The Walking Dead: World Beyond implies that the zombie virus started in France and was caused by human intervention. The post also speculates that a new antagonistic group called the Cause may be responsible for creating the variants. Another possibility is that the Cause is trying to find a cure for the virus, but their experiments have unintended consequences. AMC hints that Daryl's new show may explore the evolution and origin of the zombie virus.
