Hannah and Abba—Hebrew for "Dad"—are spending time together in nature on Tu B'Shevat, the Jewish Arbor Day. As Abba rests under a carob tree, Hannah declares that she wants to climb a tree. The carob tree's trunk is too skinny, but can she climb a eucalyptus tree or a pine tree or an olive tree? When each poses a challenge—for being too scratchy, for not having footholds—Abba offers new inspiration for climbing and insight into what Hannah and the carob tree share in common.

The ABBA Tradition is the spiritual and mystical tradition that lies deep within and behind western religions and modern cultures. It is the worldview that is the source, substance, and infrastructure of Judaism and Christianity. It is the one great tradition behind the Hebrew and Greek languages, the Old and New Testaments, ancient religions, and modern science. Whether you call it Kabbalah, the Four World Tradition or something else, it transcends the separation between the historic faiths and, more importantly, teaches a way of reconciliation and reunion. This book helps Christians discover the profound Jewish tradition that Jesus of Nazareth lived and taught, and also highlights one of the greatest Jews of all time: Joshua be Miriam of Nazareth, who first brought the Gentile nations to the holy one of Israel. Heal the wounds that separate us one from another, Jew from Christian, brother from sister – and discover the interrelated worlds of physicality, psychality, spirituality, and divinity with the wisdom in this book.

The field of Genetics is rapidly evolving and new medical breakthroughs are occuring as a result of advances in knowledge gained from genetics research. Advances in Genetics continually publishes important, timely reviews from leaders in the field that cover a broad range of topics of interest to geneticists and their colleagues in affiliated disciplines.

How do ecological and evolutionary factors maintain the balance of diverse species (including humans) in an ecosystem? With examples ranging from Bhutan to California, Christopher Wills explains the processes. He also presents striking evidence that human populations have adapted genetically to environments.

Population Genetics and Microevolutionary Theory Explore the fundamentals of the biological implications of population genetic theory In the newly revised Second Edition of Population Genetics and Microevolutionary Theory, accomplished researcher and author Alan R. Templeton delivers a fulsome discussion of population genetics with coverage of exciting new developments in the field, including new discoveries in epigenetics and genome-wide studies. The book prepares students to successfully apply population genetics analytical tools by providing a solid foundation in microevolutionary theory. The book emphasizes that population structure forms the underlying template upon which quantitative genetics and natural selection operate and is a must-read for future population and evolutionary geneticists and those who wish to work in genetic epidemiology or conservation biology. You’ll learn about a wide array of topics, including quantitative genetics, the interactions of natural selection with other evolutionary forces, and selection in heterogeneous environments and age-structured populations. Appendices that cover genetic survey techniques and probability and statistics conclude the book. Readers will also benefit from the inclusion of: A thorough introduction to population genetics, including the scope of the subject, its premises, and the Hardy-Weinberg Model of Microevolution An exploration of systems of mating, including a treatment of the use of runs of homozygosity to show pedigree inbreeding in distant ancestors A practical discussion of genetic drift, including the use of effective sizes in conservation biology (with a discussion of African rhinos as an example) A concise examination of coalescence, including a treatment of the infinite sites model Perfect for graduate students in genetics and evolutionary biology programs and advanced undergraduate biology majors, Population Genetics and Microevolutionary Theory will also earn a place in the libraries of students taking courses in conservation biology, human genetics, bioinformatics, and genomics.
