We did not need to defend against predators since at least a thousand years, very likely for a much longer time frame. The latest enemies weren't some wild beast, it was famine and infighting. I doubt we have really moved beyond either to be honest. But still, the point I was trying to make is that if this is relevant to shape behavior and didn't happen yet, it doesn't have to happen between 1970 and 2023.
