I agree with Zaqaria.

After all, we are just cells ourselves.

Our specific collection of cells is what we call 'human'.

There's no reason for cells to suddenly become somehow more intelligent when they are combined. They are just communicating with each other, that's all. They are still, individually, not 'intelligent'.

It's like if you get a group of mentally retarded people in a room, they aren't going to become smarter, and it's unlikely that they would create something that they couldn't have alone. Unless you suggest that individual cells can learn from each other.
