Breathing Life into Biology [PDF ebook] 

This book shows that contemporary biology is focused almost exclusively on genes and molecules. This approach, despite giving rise to exciting developments, such as DNA sequencing and genetic engineering, does not take into account the living organisms themselves. This text redresses this imbalance: firstly, by providing a sketch of a fully-fledged theory of what living organisms are; and then putting this theory to work by recounting the story of the evolution of living organisms on Earth.
