Dr. Denise Herzing began her research with a pod of spotted dolphins in the 1980s. Now, almost three decades later, she has forged strong ties with many of these individuals, has witnessed and recorded them feeding, playing, fighting, mating, giving birth and communicating. Dolphin Diaries is an account of Herzing's research and her surprising findings on wild dolphin behavior, interaction, and communication. Readers will be drawn into the highs and lows—the births and deaths, the discovery of unique and personalized behaviors, the threats dolphins face from environmental changes, and the many funny and wonderful encounters Denise painstakingly documented over many years. This is the perfect book for anyone who loves these incredibly versatile and intelligent creatures and wants to find out more than the dolphin show at the zoo can offer. Herzing is a true pioneer in her field and deserves a place in the pantheon of naturalists and scientists next to Dian Fossey and Jane Goodall.

The natural world can be viewed as a continuously changing complex system comprising variable units that do not conform to any stable plan. Within this framework, human evolution is not the story of the past that created Homo sapiens and then handed this account over to written history. It is the ongoing process that shapes us now and will shape us in the future, body and mind. We must understand it in order to survive and be able to direct it to our advantage. The Dynamic Human presents a general theory of how humans function as a multi-individual system embedded in the natural world. The authors employ a unified approach of systems theory to outline forces that direct ongoing human evolution and produce its outcomes in terms of the past, present and future. Readers will find a perspective on the human place in nature, through a brief account of the past human evolution over 10 million years ago, a discussion of the earliest appearance of humans some 2 million years ago, and a description of the mechanisms of the changes in the gene pool of humans from generation-to-generation. Understanding the forces involved in these mechanisms (physical and mental growth and development) may allow us to understand world better. The Dynamic Human presents a simplified perspective on human evolution for all readers interested in a discourse on the origins, nature and future of human beings.
