“Our modern lives are very different from those of early humans, who hunted and gathered to survive. Their reverence for the natural world is evident in the early murals of wildlife they painted on cave walls and in the stylized visions of life they sculpted from bone and ivory. Our lives reflect remnants of our ancestral attachment to nature and the diversity of life - the concept of biophilia that was introduced early in this chapter. We evolved in natural environments rich in biodiversity, and we still have a biophilia for such settings. Indeed, our biophilia may be innate, an evolutionary product of natural selection acting on a brainy species who survival depended on a close connection to the environment and a practical appreciation of plants and animals. Our appreciation of life guides the field of biology today. We celebrate life by deciphering he genetic code that makes each species unique. We embrace life by using fossils and DNA to chronicle evolution through time. We preserve life through our efforts to classify and protect the millions of species on Earth. We respect life by using nature responsibly and reverently to improve human welfare. Biology is the scientific expression of our desire to know nature. We are most likely to protect what we appreciate, and we are mostly likely to appreciate what we understand. By learning about the processes and diversity of life, we also become more aware of ourselves and our place in the biosphere. We hope this text has served you well in this lifelong adventure.”
