Thus far in the history of biology, two, and only two, fundamental principles have come to light that pervade and unify the entire science-the cell theory and the concept of evolution. While it is true that recently opened fields of inves tigation have given rise to several generalizations of wide impact, such as the universality of DNA and the energetic dynamics of ecology, closer inspection reveals them to be part and parcel of either of the first two mentioned. Because in the final analysis energy can act upon an organism solely at the cellular level, its effects may be perceived basically to represent one facet of cell me tabolism. Similarly, because the DNA theory centers upon the means by which cells build proteins and reproduce themselves, it too proves to be only one more, even though an exciting, aspect of the cell theory. In fact, if the matter is given closer scrutiny, evolution itself can be viewed as being a fundamental portion of the cell concept, for its effects arise only as a consequence of changes in the cell's genetic apparatus accumulating over geological time. Or, if one wishes, the diametrically opposite standpoint may be taken. For, if current concepts of the origin of life hold any validity, the evolution of precellular organisms from the primordial biochemicals must have proceeded over many eons of time prior to the advent of even the most primitive cell.

Why should the gene be suggested to be inconstant when the contrary view, that gene structure is invariant except through mutagenic processes induced by potent external factors, has long been a universal doctrine of genetics? Indeed, during the early part of the present century before mutation was recognized as being of general occurrence, the seeming unvarying nature of the gene led to skepticism regarding the validity of the evolutionary theory; only later could the origins of the morphological differences between individuals and species be attributed to a combination of mutation and evolution, involving natural forces selecting between favorable and unfavorable genetic changes. But during the past several decades, as knowledge of the macromolecular constitution of or ganisms has increased to the point where even the primary structures of the genes themselves are being revealed on a routine basis, it has become increas ingly difficult to ascribe all the resulting observations to ordinary mutagenesis and natural selection. Some more profound mechanism often seems to be present that influences both the constancy and inconstancy of the genes, an ap paratus whose existence this study hopes to reveal. In seeking to demonstrate the universality of this mechanism, data are sought through the numerous activities of organisms of many types wherever gene action changes are manifest.

When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers.
