Family Tree: Rooted in Survival tells the never-before-told- true story of three family branches and their struggles to survive the horrors of the Holocaust. Family members are separated from one another and must find the will to survive on their own. Will their will to survive be enough to withstand the Nazi crimes against humanity? Will they find one another again and be able to make a life after survival?

One of the charms of mathematics is the contrast between its generality and its applicability to concrete, even everyday, problems. Branching processes are typical in this. Their niche of mathematics is the abstract pattern of reproduction, sets of individuals changing size and composition through their members reproducing; in other words, what Plato might have called the pure idea behind demography, population biology, cell kinetics, molecular replication, or nuclear ?ssion, had he known these scienti?c ?elds. Even in the performance of algorithms for sorting and classi?cation there is an inkling of the same pattern. In special cases, general properties of the abstract ideal then interact with the physical or biological or whatever properties at hand. But the population, or bran- ing, pattern is strong; it tends to dominate, and here lies the reason for the extreme usefulness of branching processes in diverse applications. Branching is a clean and beautiful mathematical pattern, with an intellectually challenging intrinsic structure, and it pervades the phenomena it underlies.

History Within explores how the life sciences have contributed to public and popular history and to moral and political visions for a just society of the future. It shows how the sciences that deal with the evolutionary history of human groups and of humankind are powerful producers of origin narratives and experiences of kinship and belonging. Marianne Sommer looks at the collecting efforts of three key scientistsHenry Fairfield Osborn, Julian Huxley, and Luca-Luigi Cavalli-Sforzathat render the interactive creation of bio-historical knowledge possible in the first place and asks how their scientific data was translated into more broadly meaningful narratives, images, and exhibits. The bones, organisms, and molecules they studied acquire political value, she argues, in negotiations over issues of interpretation and how scientific results ought to be communicated to the public. History Within is an essential history of biology in the twentieth and twenty-first centuries."

Leading scientists bring the controversy over Gaia up to date by exploring a broad range of recent thinking on Gaia theory.

During the last few years the science of human genetics has been expanding almost explosively. Original papers dealing with different aspects of the subject are appearing at an increasingly rapid rate in a very wide range of journals, and it becomes more and more difficult for the geneticist and virtually impossible for the non geneticist to keep track of the develop ments. Furthermore, new observations and discoveries relevant to an overall understanding of the subject result from investigations using very diverse techniques and methodologies and originating in a variety of different disciplines. Thus, investigations in such various fields as enzymology, immunology, protein chemistry, cytology, pediatrics, neurology, internal medicine, anthropology, and mathematical and statistical genetics, to name but a few, have each contributed results and ideas of general significance to the study of human genetics. Not surprisingly it is often difficult for workers in one branch of the subject to assess and assimilate findings made in another. This can be a serious limiting factor on the rate of progress. Thus, there appears to be a real need for critical review articles which summarize the positions reached in different areas, and it is hoped that "Advances in Human Genetics" will help to meet this requirement. Each of the contributors has been asked to write an account of the position that has been reached in the investigations of a specific topic in one of the branches of human genetics.
