One of the most terrifying things about zombies is their singular motivation. Relentless pursuit of brains, at all costs. Though they may seem to function as a hive mind when in a horde, they don't actually work together at all. They are an autonomous mob...

That being said. There is every reason to think that the zombie virus that doomed them to their ghoulish existence would mutate over time and perhaps lead to a more refined, even cultured, zombie. This evolution would no doubt be met with distain from the more conservative and nostalgic zombies who would whine and complain for a return to a more traditional and/or biblical zombian society.
