African fossil sites from the Middle and earliest Late Pleistocene.

Sites discussed in the text are highlighted in pink here. Geological age estimations for each fossil hominin assemblage are given in Table 1, along with references.

Phylogenetic scenarios for H. naledi.

A simplified cladogram of Homo, with the possible placements of H. naledi indicated. The cladogram places A. africanus as an outgroup to the Homo + Au. sediba clade, as consistent with nearly all phylogenetic analyses of these species (Berger et al., 2010; Dembo et al., 2015, 2016). To simplify the tree, we have omitted H. antecessor, H. heidelbergensis and Neanderthals, which all phylogenetic analyses place as sisters to H. sapiens relative to H. erectus. There is no present consensus about the branching order among H. habilis, H. rudolfensis, H. floresiensis and Au. sediba (Dembo et al., 2015, 2016), and so these are depicted as a polytomy.

Table 1

Significant hominin fossil remains from the Middle and Early Late Pleistocene of Africa. Included are those sites that have geological age estimates between 780,000 and 120,000 years ago, and some sites for which claims of Middle Pleistocene age have been made but without chronometric support. Sites denoted here with ‘no date’ are those for which no chronometric determinations based on samples of hominin material or securely associated faunal remains have been reported in the literature. Some chronometric determinations that were based only on morphology or associated fauna have given rise to broad age estimations; we omit the details of such determinations here. Some additional sites with fragmentary remains, especially isolated dental remains, are not listed. The first four entries (KNM-OL 45500, OH 12, Daka and Buia) are older than the beginning of the Middle Pleistocene but are included because they are discussed in text.
