Cellular division is what makes us grow. I think you mean evolved from dinosaurs right? Maybe we did.

Each cell in our body has a defined life time. At the end of each DNA molecule is a series of nucleac acids called telomeres. Each time a cell reproduces, one of these telomeres is deleted. When there are no more telomeres, the cell fails to reproduce. When tissues of our body are no longer replaced our body ages.
