In mid-twentieth-century paleoanthropology, the discovery of taphonomically altered faunal assemblies alongside *Australopithecus africanus* fossils led Raymond Dart to formulate the 'osteodontokeratic' culture hypothesis—positing that early hominins systematically crafted weapons from bone, tooth, and horn. Dart interpreted fractured baboon crania at Makapansgat as definitive evidence of predatory violence and deliberate clubbing executed by *A. africanus*. However, subsequent taphonomic reassessments initiated by C. K. Brain demonstrated that these characteristic fracture patterns were almost entirely attributable to the predatory mechanics of leopards (*Panthera pardus*) and passive geological compaction within cave shafts. Brain’s meticulous counts of skeletal element representation revealed that the disproportionate survival of durable bones—such as mandibles and distal humeri—reflected differential preservation dynamics rather than selective tool curation by hominins. While Brain successfully dismantled the premise that *A. africanus* was a bloodthirsty apex hunter, some modern researchers argue that his total attribution of bone accumulations to non-hominin agents overlooked subtle cut-marks and fracture morphologies present on a minor subset of the Makapansgat fauna, which indicate opportunistic scavenging of carnivore kills by early hominins.
Based on the passage, which of the following can be validly inferred regarding C. K. Brain’s analysis of the Makapansgat fossil deposits?
- It relied on evaluating the relative survival rates of specific anatomical structures to challenge the assumption of intentional hominin tool selection.Answer
- BIt definitively established that early hominins engaged in no physical interactions with large carnivores in their local environment.
- CIt concluded that fractured baboon skulls were produced primarily through hominin weapon usage rather than natural predatory processes.
- DIt demonstrated that taphonomic methodology is fundamentally incapable of differentiating between carnivore damage and early hominin scavenging.
- EIt completely disproved Dart’s work by demonstrating that hominins never entered or inhabited the cave systems where fossils were found.
