Techniques of recovery include: Data collection and analysis is oriented to answer questions of subsistence, mobility or settlement patterns, and economy.Though fossils of hominids have been found dating back millions of years, the earliest known Homo sapiens remains are considered to be a group of bones found at the Omo Kibish Formation, near the Ethiopian Kibish Mountains.

During this same time period, freshwater mollusk shells start to show up.Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery.This also works with stone tools which are found abundantly at different sites and across long periods of time.Stratigraphic dating is based on the principle of depositional superposition of layers of sediments called strata.
