It’s been previously theorized that zombies hunt in packs because of a dependence on their sense of touch to identify prey. But ZRS Researcher, Haley Amara, suggests that a more developed social structure could be at work, citing behavioral evidence from the common bee.
She points out that bees, along with ants and wasps, are able to carry out complex tasks involving thousands of individual participants with little or no communication.
“They’re all doing their own thing, completely unaware of what their fellow bees are up to, but still they present a unified front, each of them marching towards a common goal.”
Amara goes on the argue that the aggressive behaviors created by the hive mind of bees is extremely similar to a typical depiction of a zombie outbreak. A horde of zombies doesn’t work together or communicate in any traditional sense. But then again they are only a real threat when they present a unified front, attacking as a group.
A colony of bees is often described by experts as being functionally one creature. Each bee is just a part of a single entity. Looking at the undead in a similar way would help to explain why they possess such a complete disregard for their individual well being. The destruction of one particular zombie is meaningless to the horde, so long as they continue moving forward towards the ultimate objective of devouring the entire human race.
