There’s never a bad time to post some Carl Sagan.
The Planetary Society:
In the second episode of Cosmos, “One Voice in the Cosmic Fugue,” we switch gears from the very big to the very small – from the cosmos to a microcosm. If the first episode was all about the origin of the universe and understanding our place within it, the second is about the origin of species and our place within the chaotic history of life on Earth.
It’s a natural progression, particularly for a show about the “interconnectedness of all things,” as Sagan explained in episode one. There is no more beautiful example than the shared molecular chemistry of life on Earth. That the processes of DNA replication and protein generation are the same in humans as they are in the smallest single-cell organism – and all directed by the same molecular code – remains a stunning insight of the modern era. We all share the same heritage. We all come from the same stuff.
