PREFACE
CHAPTER I THE REALITY OF EVOLUTION
CHAPTER II EVIDENCES OF THE EVOLUTION OF MENTAL POWERS
CHAPTER III EVIDENCES OF THE EVOLUTION OF THE MORAL SENSE
CHAPTER IV THE EVOLUTION OF HUMAN MORALITY
In the opening chapter the author invites listeners on a thoughtful tour of animal behavior, showing how the simplest creatures reveal the roots of our own thinking and feeling. By weaving vivid first‑hand observations with clear scientific explanations, the book demonstrates that the same processes shaping a squirrel’s foraging or a bird’s song also laid the groundwork for human conscience. This approach makes the often abstract debates about evolution feel concrete and relatable.
From the curious case of vestigial mammary tissue in male embryos to the striking parallels between early human development and hermaphroditic organisms, each example serves as a key to unlocking the larger story of moral evolution. The narrator urges a skeptical, hands‑on attitude, encouraging listeners to question received wisdom rather than accept fashionably trendy ideas. As a result, the work offers both a rigorous look at biological evidence and a fresh perspective on why we, as a species, behave the way we do.
