Episode notes
Rings Younger Than Sharks?
- Saturn's rings may be only 10–100 million years old based on dust accumulation measurements by Cassini.
- Shark ancestors' fossils date back ~450 million years, making sharks much older than the rings unless rings self-cleanse via Saturn's pull.
Ghost Shark's Forehead Teeth
- The ghost shark (spotted ratfish) has tiny tooth-like structures on its forehead called a tenaculum used to grip females during mating.
- Scientists described these forehead structures as teeth, challenging the idea that teeth are strictly oral.
How Blade Runner Got Its Title
- Ridley Scott acquired film rights to William Burroughs' Blade Runner just to use the title for his adaptation of Philip K. Dick's novel.
- The movie's title traces through Alan E. Nourse to Burroughs then to the Ridley Scott film, creating a tangled adaptation lineage.
