Nature Fast and Nature Slow

Book excerpt: This book is a vision of biology set within the entire timescale of the universe. It is about the timing of life, from microsecond movements to evolutionary changes over millions of years. Human consciousness is riveted to seconds, but a split-second time delay in perception means that we are unaware of anything until it has already happened. We live in the very recent past. Over longer timescales, this book examines the lifespans of the oldest organisms, prospects for human life extension, the evolution of whales and turtles, and the explosive beginning of life four billion years ago. With its poetry, social commentary, and humor, this book will appeal to everyone interested in the natural world.
