Early–Middle Pleistocene Transitions: The Land–Ocean Evidence
The Early–Middle Pleistocene transition (around 1.2 to 0.5 Ma) marks a profound shift in Earth’s climate state. Low-amplitude 41 ka climate cycles, dominating the earlier part of the Pleistocene, gave way progressively to a 100 ka rhythm of increased amplitude that characterizes our present glacial—interglacial world. This volume assesses the biotic and physical response to this transition both on land and in the oceans: indeed it examines the very nature of Quaternary climate change. Milankovitch theory, palaeoceanography using isotopes and microfossils, marine organic geochemistry, tephrochronology, the record of loess and soil deposition, terrestrial vegetationa! change, and the migration and evolution of hominins as well as other large and small mammals, are all considered. These themes combine to explore the very origins of our present biota.

Whereas geoscience depends in part on the classical nomological method of the environmental sciences, it is also distinguished by a discrete set of logical procedures that lend themselves to forensic analysis. It has been argued that, as geology is a derivative science, it only partially lives up to the classical model of scientific reasoning. It does, however, provide a model of scientific reasoning based on interpretive techniques and its historical nature. Reasoning in geoscience offers a method that is applicable to the uncertainties and complexities of real-life situations because we are seldom in possession of all the data that...
