Читать книгу Your Body - The Fish That Evolved - Dr. Keith Harrison - Страница 3

Preface

T here is no aspect of nature more obvious or more personal than our own body, but how much do we really know about it? Why do we have two arms and two legs, not four arms or six legs? Why do we have ribs across our chest but not across our stomach? Why do our elbows and our knees bend in opposite directions (and have you ever noticed)? This book sets out to answer these questions and others as it traces the evolution of every one of us, not from our cousins the apes but from our more distant ancestors – the fish.
