The Cincinnati Zoo recently canceled a joint ticket promotion with the nearby Creation Museum in Kentucky.

Some scientists and bloggers complained the zoo should not work with a religious museum that rejects evolution.

The promotion was a 2-for-1 deal to the zoo's holiday light show and the Creation Museum's live nativity performance.

The museum's president Ken Ham says, "It's a pity that intolerant people have pushed for our expulsion simply because of our Christian faith."
