Why are there ridges on the roof of our mouths?

Just curious. My dog has them all the way back, I just have a few toward the front. What is the point of this? Why does my dog have more?Why are there ridges on the roof of our mouths?
They help with manipulating food and swallowing. Your dog has more because a dog's mouth is larger than a human's.
