Abstract

This chapter is built around three case studies of biological investigations carried out not only in three very different areas of biology, but also in three different settings: the experimental laboratory, the field under natural conditions, and in historical time using paleontology and the fossil record to answer questions about the evolutionary development of life on earth. The first, laboratory-based case concerns the investigation into the mechanism by which nerve fibers growing out from the central nervous system “find” their way to very specific target sites (muscles, for example) in the peripheral areas of the animal body. This work led to the discovery of Nerve Growth Factor (NGF) in the 1950s–1970s. The second, field-based case comes from a long-term investigation into the homing behavior in salmon: namely, an attempt to find out how adult salmon find their way from the ocean to the precise stream in which they hatched three or four years earlier. The third, historical case, involves the quest of evolutionary biologists to understand the causal factors in the extinction of the dinosaurs as part of a larger phenomenon known as “mass extinction”, during which numerous groups of organism all become extinct in a relatively short period of geological time.
