The study of early human diets is important in understanding the evolution of the human species. The size and shape of our skulls and teeth are directly linked with culture and diet. As foods became softer over time (primarily due to the use of fire and cooking) and meat became more common in the human diet, the size of human dentition decreased. Along with this reduction in the size of teeth, cooked foods, especially meats, made increased calories and nutrition available and also prompted brain growth. The most direct evidence of meat eating among early humans is butcher marks found on bone, estimated to be from as early as 3.4–2.6 million years ago (Wild 2019; Pobiner 2013). The earliest evidence of humans cooking a carbohydrate source is charred tubers recently identified by archaeologist Cynthia Larbey (Wild 2019) at Blombos Cave, in the Klasies River site in South Africa, and dated to 120,000 BP. Excavations at the archaeological site Shubayqa 1 in Jordan have uncovered the earliest evidence of charred breadcrumbs, indicating that humans were baking bread as early as 14,500 BP (Richter and Arranz-Otaegui 2018). From meat to potatoes to bread, humans and their diets have adapted to changing ways of life.
In the archaeological record, food evidence takes many forms. It may be a hearth or pottery container with food or drink residue, butchered animal bones, coprolites (fossilized fecal material), tools used in food processing, baskets or pottery used for storing food, or even garbage dumps or shell middens (large collections of discarded shells.) In historical sites, there may even be preserved food remains, such as corn kernels or alcoholic beverages still enclosed in containers. Studying food helps anthropologists better understand many aspects of human existence and culture, including the rhythms and activities of daily life, food exchange and preparation, feasting, ritual activities, population density, length of settlement at a site, division of labor, seasonal activities, diet and health, cultural traditions and preferences, and even social status within a group. Food is connected with almost all human activities.
