Understanding paleoclimates has been an important component of archaeological research for over a century. Human settlement, mobility, and subsistence activities are predicated on interactions with the natural world, and by reconstructing the broader environmental context, archaeologists can recognize the primary external catalyst of cultural change. Modern paleoenvironmental reconstruction methods employ techniques developed over the last century as well as those that are at the frontiers of scientific inquiry. Archaeologists intent on providing basic environmental context must first describe the sedimentology of surficial deposits in order to understand landform evolution. Furthermore, descriptions of soils, which form in stable, weathered sedimentary deposits, are critical indicators of past climate. Soils are first described in excavation test units using macro-scale classification schemes, but increasingly microscopic techniques such as soil micromorphology in thin sections and DNA sequences of endemic microbiota are being used. Various types of plant and animal communities hosted in archaeological deposits also provide critical environmental details as they are often temperature and precipitation dependent. Generally speaking, the simpler and smaller the organism is, the more restricted its habitat tends to be. Therefore, microfauna and floral remains often provide the greatest level of precision in environmental reconstruction. Finally, light stable isotopes of carbon, oxygen, and nitrogen can be assayed from a wide variety of organic matter, and they provide specific information about biotic communities and precipitation that are useful to understand paleoenvironments. The simultaneous integration of multiple lines of evidence is being performed in archaeological research projects across the African continent and provides the best means to fully comprehend the framework in which human biological and cultural evolution occurred.
