From what I have read zombies have no intellect. Their sole purpose is to seek prey. They have no higher level brain function.
How would a zombie approaching a house know its weak points? If they have no memory from their previous life, how would they know what a door was or a window They would attack all points equally.
Literature and movies show them attacking doors and windows but why?
Wouldn't they equally exert their energy against walls.
Zombies attacking weak ponts would indicate intellingence. If they have none, simply camoflouging entrance points would fool them.
