Recent advances that allow scientists to quickly and accurately sequence a genome have revolutionized our view of the structure and function of genes as well as our understanding of evolution. A new era of genetics is underway, one that allows us to fully embrace Dobzhansky's famous statement that "Nothing in biology makes sense except in the light of evolution". Genetics: Genes, Genomes, and Evolution presents the fundamental principles of genetics and molecular biology from an evolutionary perspective as informed by genome analysis.By using what has been learned from the analyses of bacterial and eukaryotic genomes as its basis, the book unites evolution, genomics, and genetics in one narrative approach. Genomic analysis is inherently both molecular and evolutionary, and every chapter is approached from this unified perspective. Similarly, genomic studies have provided a deeper appreciation of the profound relationships between all organisms - something reflected in the book's integrated discussion of bacterial and eukaryotic evolution, genetics and genomics. It is an approach that provides students with a uniquely flexible and contemporary view of genetics, genomics, and evolution.

Avoiding infection has always been expensive. Some human populations escaped tropical infections by migrating into cold climates but then had to procure fuel, warm clothing, durable housing, and crops from a short growing season. Waterborne infections were averted by owning your own well or supporting a community reservoir. Everyone got vaccines in rich countries, while people in others got them later if at all. Antimicrobial agents seemed at first to be an exception. They did not need to be delivered through a cold chain and to everyone, as vaccines did. They had to be given only to infected patients and often then as relatively cheap injectables or pills off a shelf for only a few days to get astonishing cures. Antimicrobials not only were better than most other innovations but also reached more of the world’s people sooner. The problem appeared later. After each new antimicrobial became widely used, genes expressing resistance to it began to emerge and spread through bacterial populations. Patients infected with bacteria expressing such resistance genes then failed treatment and remained infected or died. Growing resistance to antimicrobial agents began to take away more and more of the cures that the agents had brought.

Infectious disease is the most common cause of illness and death in Africa, yet health practitioners routinely fail to identify causative microorganisms in most patients. As a result, patients often do not receive the right medicine in time to cure them promptly even when such medicine is available, outbreaks are larger and more devastating than they should be, and the impact of control interventions is difficult to measure. Wrong prescriptions and prolonged infections amount to needless costs for patients and for health systems. In Divining without Seeds, Iruka N. Okeke forcefully argues that laboratory diagnostics are essential to the effective practice of medicine in Africa.The diversity of endemic life-threatening infections and limited public health resources in tropical Africa make the need for basic laboratory diagnostic support even more acute than in other parts of the world. This book gathers compelling case studies of inadequate diagnoses of diseases ranging from fevers—including malaria—to respiratory infections and sexually transmitted diseases. The inherited and widely prevalent health clinic model, which excludes or diminishes the hospital laboratory, is flawed, to often devastating effect. Fortunately, there are new technologies that make it possible to inexpensively implement testing at the primary care level. Divining without Seeds makes clear that routine use of appropriate diagnostic support should be part of every drug delivery plan in Africa and that diagnostic development should be given high priority.
