This book reviews the complex adaptive systems and their geometric hallmarks in the nature. It discusses the emergence of life and debates the related proposed hypotheses. It examines the process of evolution and the roles that chance and necessity might play. It talks about the development of sex at the expense of immortality and reviews programmed cell death (apoptosis) and its role on the embryonic growth and other biological processes, such as development of cancer. It examines the scientific evidence of the origin of modern humans. Evidence that shows we are all closely related, and share far more genetic similarities than the 'œracial' phenotypic features such as skin color, hair texture or the shapes of our nose or lips. It reviews the enormous environmental and socioeconomic problems we are facing today and reminds us that we are all in this together, and only steady collective and collaborative global efforts would be able to solve the worldwide problems.
