T]he Origin of Species proposed a radically new idea, conceiving of time not as a power but as a factor whose effect could be perceived directly in distinct but complementary forms fossils, embryos, and rudimentary organs. The fossil was petrified time the embryo, operative time the rudimentary organ, retarded time. Together these bits of evidence constituted the archives of biological history —... 

A closer look at biological history shows how few genetic differences are likely to be correlated with race, and thus how unlikely it is that recogniz-...

There is considerable evidence in the literature that Western coals behave differently toward liquefaction than do coals from the East or from the Interior (1). The differences can be attributed to the geological and biological history of these regions and yielded a different skeletal structure for Western coal Coal liquefaction studies have demonstrated that the direct liquefaction of Western coals is more problematic and requires more severe conditions than for Eastern coals. 

The Shroud is a linen textile that consists of cellulose derived from flax. Each of the constituent elements of the cellulose (hydrogen, carbon, and oxygen) exists in several stable isotopic forms. The lighter isotopes 1H, 12C, and leO are generally more abundant, but smaller concentrations of the heavier D (2H), 13C, and lsO are also present in measurable amounts. In any sample, the relative quantities D/H, 13C/12C, and 180/160 depend on the physical, chemical, and biological history of the material. 

A reasonable ambition for model reactions is that their mechanisms ought to contain some dues about the mechanism of the enzyme-catalyzed reaction also. It has long been realized that it is fruitless simply to buUd the model-reaction mechanism into an enzyme active site. Such a procedure would entail the view that the factors present and at work in the model system render a complete account of the biological history of the enzyme. There is no reason to expect this to be so, and many reasons to think it would not be so. In the simplest sense, a given enzyme must occupy a niche in a metabolic network that may require its regulation and may influence its structure and mechanistic potentialities in ways that cannot be derived from non-enzymic studies. 

Nor, as we already know, is it an easy process prenatal development is the most vulnerable period in the biological history of any human being. There are entire ranges of prenatal effects... 

The reductionist approach to evolution. .. has proved enormously successful in illuminating the ultimate basis for the transformation of one organ into another, or even one species into another but these momentous discoveries do not explain the course of biological history. The description of a cast of characters alone does not determine the shape of a drama. Richard Fortey, in a review of Simon Conway Morris s The Crucible of Creation...
