Treat yourself to reading this book by Bret Stetka, A History of the Human Brain: From the Sea Sponge to CRISPR, How Our Brain Evolved. On the subjects that draw your interest, and its extraordinary depiction of the arc of the evolution of our human brain. Which is, of course, the non-linear, jagged progression to today’s homo sapiens – and where we might be going. Read my review of Stetka's new book on Psychology Today.
