“I like to define biology as the history of the earth and all its life — past, present, and future.”
Preface to Humane Biology Projects (1961) by the Animal Welfare Institute
Context: I like to define biology as the history of the earth and all its life — past, present, and future. To understand biology is to understand that all life is linked to the earth from which it came; it is to understand that the stream of life, flowing out of the dim past into the uncertain future, is in reality a unified force, though composed of an infinite number and variety of separate lives.
