Darwin Day is Every Day




The abundance on Earth of covergent evolution (ie. the eye has evolved 40 different times) suggests an enormous multitude of life pathways besides that observed on Earth. Just look at the multitude of pathways on Earth. Any observation we ever make from Earth at other planetary bodies is a tiny snapshot in their multi-billion year story, and ours. We may face the conundrum of having life everywhere in the Universe, but due to the size of the Universe (which alone makes this a certainty), all that life will remain utterly unobservable from Earth for thousands of our lifetimes.
