Zombies are meant to be mindless creatures that have no trace left of their humanity or sense of rationality. So I don’t get why is it that they’re able to still use their ablities as if they actually have the smarts for it?
Zombies operate differently in anything they’re in.
Some zombies can run (World War Z, I Am Legend), others can’t (The Walking Dead)
Some can speak, or at least mumble as a reply (Army Of The Dead), others can’t (most Zombie films/tv shows they can’t)
Some Zombies can get pregnant, or at least carry a child in their womb even if they become zombified (Dawn Of The Dead, Army Of The Dead), others can’t.
