A hidden history of human evolution has been written, but very few people know about the history of disabled people who have been walking side by side able bodied people since the beginning of time. In this book we shall discover the two true elements which cause our bodies to change, biological and environmental changes that we all face before and during life. History has often regarded disabled people as 'imperfect', but what if they were special people who are unique, and a valuable part of the broader rainbow of human diversity? This book shall unlock the padlock into human history that has rarely been talked about before. There is more to us than originally thought.
