Not only looking down is worthwhile, but also looking ahead.
So this is my collection of pictures of tree bark from Arizona. The textures are beautiful, and one wonders why the trees are making this effort.
After all, the visible outer layer is just dead cells.
So, more precisely: Does the beauty we (or is it just me?) see in these structures provide some evolutionary advantage?
Not for the trees, I am afraid.
But maybe for us,
because the beauty we believe to see helps to keep looking forward, despite all the decay.
