I finished reading Other Minds: The Octopus and the Evolution of Intelligent Life by Peter Godfrey-Smith.📚

I quite liked the first half of the book, where the author shows how life has evolved from single-cell organisms to the complex multicell combinations we have now.

The chapter about how the color change works in some of the squids was also exciting. I did not expect such a complicated mechanism to be present in animal life. The skin is a multicolor display – but apparently, not every pixel can be controlled directly. And what surprised me the most is that squids are not able to see color, so the patterns cannot be used for intentional communication at all.
