this is the DNA and evolution episode and not the chemical elements episode. the episode where Sagan throws up all the elements is the same one where he says if you want to bake an apple pie from scratch, you must first invent the universe and it focuses on atoms.
so, just saying, dont expect anything like the elements getting tossed in air move today.
If anything there could be some CGI cool stuff about the workings of cells and DNA and maybe (maybe) an homage to this famous little animation
Boo.
Ah well. Maybe we'll get a modern version of the cute little polymerases unzipping and duplicating dna with spare parts
Really psyched either way with the episode.
Edit: if they're getting into how Natural Selection sculpted the Human Eye, I really hope they go into parallel evolution as well. When you compare how mammal eyes and mollusk eyes evovled from very different mechanisms yet both being very similiar in structure (At least for Octopus eyes, things like the Nautilus have a more simple "pinhole camera" eye), it just makes you sit back and go "woah, thats rad."
Double Edit: Ooh ooh! It just hit me too, I hope they spend some time on the Cambrian Explosion and all kinds of wacky awesome shit as well like animals with fractal body designs.
