How did people figure that out?
Ever since the invention of writing, the #1 predator to humankind has been other humans, so we must go back to the time before written records to get to a time when cats were the #1 predator. My question is, in the absence of written records, how did the people of the current age determine the rate of death from the various predators?
Maybe you mean the #1 predator not including other humans?
