Spaiens: A Brief History of Humankind — Homo sapiens (us) weren't always the only game in town.

This was a recent selection on Facebook's Year of Books, which inspired me to read the free sample chapter. The topic is fascinating for product designers, but even more importantly, writing is great, which is a nice surprise! So when I got to the end, I immediately ordered it in hardcover. Looking forward to diving deeper into the Cognitive Revolution stuff.
