INSIGHT

Alien-Octopus Claim Lacks Evidence

A 2018 paper suggested octopuses descended from extraterrestrial inputs, but specialists rejected this due to lack of evidence and expertise in cephalopod biology.
The episode frames that claim as entertaining but scientifically unsupported and warns about misusing speculative papers in popular science.

INSIGHT

A Different Kind Of Brain

Cephalopods evolved a centralized brain independently from vertebrates by condensing ganglia into a head structure.
Octopus nervous systems are highly distributed: about 500 million neurons, most located in arms and suckers rather than a central brain.

INSIGHT

Suckers Are Local Processors

Fewer than 150 million of an octopus's ~500 million neurons sit in its central brain; the rest live in arms and suckers that process local information.
Each sucker acts like a 'finger-nose-tongue' with local computation and sensory autonomy, reducing central processing load.
