Huh, I guess we’re not the only ones to beat a plot device over the head until its dead, dead, dead.
One theory posits that stone age people were in to the whole walking dead thing, too:
Archaeologists working in Europe and the Middle East have recently unearthed evidence of a mysterious Stone Age “skull-smashing” culture, according to New Scientist. Human skulls buried underneath an ancient settlement in Syria were found detached from their bodies with their faces smashed in. Eerily, it appears that the skulls were exhumed and detached from their bodies several years after originally being buried. It was then that they were smashed in and reburied separate from their bodies.
