This book rec was inspired by sofe’s lil squid story. This book is about the evolution of sentient life; with a heavy emphasis on cephalopods, as their evolutionary tree branched off from our common ancestors so long ago. Octopuses have been my fav animal for ages but I hadn’t realised how cool squid are too! And cuttlefish fish! He describes the process by which they change colour and it blew my mind, they essentially have biological pixels, for cuttlefish anyway, they have two different kinds of pixel-like cells/muscles that control two different colour spectrums. It’s a really brilliant book, and for those who are put off by too sciency books (myself included tbh), this book is a philosophy/science hybrid!
