the principal method of data acquisition in archaeology, involving the systematic uncovering of archaeological remains through the removal of the deposits of soil and the other material covering them and accompanying them.
The process of methodically uncovering and searching for remains of the past. Because an excavation removes any deposits, it destroys a site forever. Archaeological evidence is almost always destroyed if it isn't buried, so excavation plays a large part in recovering this evidence. Some excavation methods are grid layout, open excavation, and quadrant method.
as an adjective, "possessing a ventral feeding groove that collects suspended particles driven into it by the beating of a posterior flagellum." Simpson et al. (2002: 239). The "excavate hypothesis" is the hypothesis that the excavate taxa are monophyletic, vis. the taxon Excavata.
The excavates are a major line of protists, often known as Excavata. The phylogenetic category Excavata includes a variety of free-living and symbiotic forms, as well as microbes varying as to whether they contain mitochondria (that is, amitochondriate versus discicristate). Excavates are usually characterized by having two, four, or more flagella with distinct ultrastructure anterior to a ventral feeding groove supported by microtubules.
