Final answer:
Archaeological and paleoanthropological excavations involve steps such as surveying the area, conducting a controlled excavation, and careful removal of artifacts.
Step-by-step explanation:
Archaeological and paleoanthropological excavations involve several steps to ensure a systematic and accurate study of artifacts and remains. The first step is conducting a survey of the area to identify potential sites and surface artifacts. This can be done by walking across the field or using technologies like drones or Go ogle Earth. Once potential sites are identified, a controlled excavation takes place, dividing the site into square sections using a grid system, allowing archaeologists to document and map artifacts in their original location. Excavation is a slow process, with careful removal of earth around fragile artifacts. Soil samples and ecofacts may be collected for further analysis.
