I find that really hard to believe. I used to be aware of a sauropod which apparently had such a huge body and tiny head, the electrical impulses from the tail to the brain (say, if a predator dinosaur was making a meal out of it's tail) would take so long to reach the head that it evolved a second brain somewhere in it's lower back. I tend to recall that such a discovery was thwarted relatively recently when the supposed second brain was merely tissue mass in the lower spine.
I would take some convincing to believe these creatures had any intelligence other than inherited basic survival instincts. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
