| 요약 | Our understanding of early hominin diets has been challenged in a number of ways over the past decade. For instance, the dental microwear exhibited by Paranthropus boisei presents no evidence of hard-object consumption despite the species' initial portrayal as "Nutcracker Man." Also, stable carbon isotope analyses suggest that C4 plants and/or fauna eating C4 plants became increasingly import hominin dietary resources beginning more than 3 million years ago. The notion that early hominins were potentially consuming significant quantities of C4 grasses and/or sedges was particularly unexpected because these plants are generally regarded as being nutritionally and mechanically unsuitable for primate consumers. Given this, there is renewed interest in understanding the mechanical and nutritional properties of potential hominin plant foods (C4 or otherwise) and how these properties are affected by their spatiotemporal distribution across and within African savanna landscapes.Here, I present mechanical and nutritional data from plant samples collected over four field seasons in the Cradle of Humankind, South Africa, and Amboseli National Park, Kenya. In each field site, transects were established in varying types of wetland, woodland, and grassland habitats, as these environments have been associated with early hominins. Within each transect the dominant grass, sedge, tree, and forb species were collected, and their relevant parts (e.g., fruits, seeds, leaves, stems, underground storage organs) were isolated for analyses. Plants, such as grasses, that are generally regarded as unsuitable for hominin consumer exhibit a range of variation that suggests they must not be considered as a mechanically and nutritionally monolithic entity. Also, there are strong differences between various plants and plant parts and that habitat and seasonal effects likely influence their potential consumption by hominins, though not in a uniform manner and, at times, in unexpected ways. Also, there are clear differences between the properties of plants growing in our southern and eastern African field sites, particularly among C4 species, which may have implications for the apparently contrasting dietary behavior of southern and eastern African Paranthropus. |
