Sahle and Gossa (1) identify 2 components of our paper with which they disagree. Their concerns are based on misunderstandings of our paleomagnetic data and the published details of the Bokol Dora 1 (BD 1) artifact assemblage. The normal paleomagnetic sequence at BD 1 cannot represent the Reunion subchron [2.128 to 2.148 Ma (2)]. This would require one or more of the following scenarios: 1) The age of the Ali Toyta Tuff (ATT) is ∼0.5 My too old. There is no evidence to support this in the 40Ar/3...

The use of space, both at the landscape and the site level, is considered an important aspect of hominin adaptations that changed through time. At the site level, spatial analyses are typically conducted on deposits thought to have a high degree of temporal resolution. Sites with highly time-averaged deposits are viewed as inferior for these analyses because repeated site visits obscure individual behavioral events. To the contrary, here, we take the view that behaviors that repeat themselves in...

It has been suggested that a shift in diet is one of the key adaptations that distinguishes the genus Homo from earlier hominins, but recent stable isotopic analyses of fossils attributed to Homo in the Turkana Basin show an increase in the consumption of C4 resources circa 1.65 million years ago, significantly after the earliest evidence for Homo in the eastern African fossil record. These data are consistent with ingesting more C4 plants, more animal tissues of C4 herbivores, or both, but it i...

The manufacture of flaked stone artifacts represents a major milestone in the technology of the human lineage. Although the earliest production of primitive stone tools, predating the genus Homo and emphasizing percussive activities, has been reported at 3.3 million years ago (Ma) from Lomekwi, Kenya, the systematic production of sharp-edged stone tools is unknown before the 2.58–2.55 Ma Oldowan assemblages from Gona, Ethiopia. The organized production of Oldowan stone artifacts is part of a sui...

Abstract The ecological and selective forces that sparked the emergence of Homo's adaptive strategy remain poorly understood. New fossil and archaeological finds call into question previous interpretations of the grade shift that drove our ancestors' evolutionary split from the australopiths. Furthermore, issues of taphonomy and scale have limited reconstructions of the hominin habitats and faunal communities that define the environmental context of these behavioral changes. The multiple ∼1.5 Ma...
