Of course they do. A grid is a tesselation of space, which means grids natrually form when there is a tendency for units of something to pack into a volume.
There are many examples:
- molecules form grids because it is a low-energy rest state.
- cells pack into grids, like the anon above mentioned
- honeycombs are grids
- many plants store fruit/seeds in pods in grid-like arrangments
I'm not sure about this, but I think that grids are more a small-scale phenomenon, and as soon as gravity begins to pull things into a point, stuff starts to resemble spheres instead.
