a-POP-tosis!


Otherwise known as programed cell death.
Natural selection occurs at the cellular level as well as that of the individual and species.
In apoptosis, the body produces many more times the number of cells it needs (in the brain, say) and then those that are selected live and the rest are instructed to die--
very quietly and neatly, without leaving inflammation or debris behind.
In a sense, then, we are continuously being carved from a block of living material;
the sculpture that is left is adapted to the environment (as well as beautiful to the eye!)
Fearfully and wonderfully made!
