The octopus within us: Cephalopods and humans share genes that began shaping intelligence dating back 518 million years

New research suggests that octopuses and humans may share an ancient evolutionary connection that helps explain the remarkable intelligence of cephalopods. According to findings discussed by New Scientist, both species could trace their cognitive complexity back to a common ancestor that lived around 518 million years ago.

This discovery points to a shared biological strategy in building intelligence across distant branches of life.

The study challenges traditional ideas about intelligence in the animal kingdom. Octopuses have long fascinated researchers with their problem-solving skills, adaptability, and curiosity, traits now better understood through their RNA innovations.

By highlighting the role of microRNAs in octopus brain development, scientists open a new window into how cognitive abilities might arise independently in very different forms of life.

The parallel between human and octopus brain complexity suggests that intelligence could emerge in many more ways than previously thought.
