Tóm tắt

Current consensus holds that the 3-million-year-old hominid Australopithecus africanus subsisted on fruits and leaves, much as the modern chimpanzee does. Stable carbon isotope analysis of A. africanus from Makapansgat Limeworks, South Africa, demonstrates that this early hominid ate not only fruits and leaves but also large quantities of carbon-13–enriched foods such as grasses and sedges or animals that ate these plants, or both. The results suggest that early hominids regularly exploited relatively open environments such as woodlands or grasslands for food. They may also suggest that hominids consumed high-quality animal foods before the development of stone tools and the origin of the genus Homo .

Carbon isotope compositions are expressed as δ 13 C values in parts per thousand (‰) relative to the Pee Dee Belemnite standard (a fossil Belemnitella americana ): δ 13 C = ( 13 C/ 12 C sample / 13 C/ 12 C standard –1 ) × 1000.

. Three milligrams of enamel powder was obtained with a rotary drill equipped with a diamond-tipped burr. Nonhominid permanent molars were sampled on the lingual surface; broken hominid permanent molars were sampled between the crown surface and the enamel-dentine junction so that external morphology and wear patterns were not altered. The powder was pretreated with 1.5% sodium hypochlorite solution to remove organic contaminants and 0.1 M acetic acid to remove diagenetic carbonates. The samples were freeze-dried and placed into individual reaction vessels in a Kiel II autocarbonate device. They were reacted with phosphoric acid at 70°C and clean dry CO 2 was obtained by cryogenic distillation. 13 C/ 12 C ratios were measured on a Finnigan MAT 252 mass spectrometer with a precision of ±0.1‰.

C 3 signatures indicate that these herbivores were browsers or browser/frugivores because there is no evidence of C 3 grasses (as evidenced by grazer δ 13 C values) at Makapansgat.
