This book is a must-read for those who wish for a happier and healthier world for our children and grandchildren. Professor Mark Williams provides a clear and understandable picture of how our brain has evolved, and what that means for us, and our descendants. He writes with clarity and good humor, referring to evidence-based research. The Connected Species is an excellent companion to Yuval Noah Harari’s Sapiens and 21 Lessons for the 21st Century.
