If you look closely at beach sand, you may find some grains that stand out. They are shaped like spirals, stars, or striated cones.
Unexpected benefits may come from a steady rain of meteoric dust onto the planet.
The jewels of the microbial world, when seen with new nano-scale imaging techniques, look like little modernist cathedrals.
As imaging techniques approach nanometer resolution, the detailed workings of molecular mechanisms reveal precision engineering designs.
There are things going on in cells that make sense only if a designing intelligence saw a need and planned for it in advance.
