These two paths diverged over when our last common ancestor was likely a tiny, primitive worm. This means the "mind" of an octopus was built using an entirely different biological "blueprint" than our own. Key Scientific and Philosophical Arguments

While generally solitary, the author discusses "Octopolis," a unique site off Australia where octopuses live in close proximity and exhibit rare social behaviors. This suggests that social interaction might be an overlooked driver of cephalopod intelligence.

Octopuses possess massive brains and incredible intelligence but live only one to two years . The author uses the Medawar-Williams theory of aging to explain this: because octopuses are so vulnerable to predators in the wild, evolution never selected for a longer life. These two paths diverged over when our last

The book's central premise is that high-level intelligence evolved at least on Earth: Vertebrates: Leads to humans, mammals, and birds. Cephalopods: Leads to octopuses, squid, and cuttlefish. This suggests that social interaction might be an
