Middle Pliocene hominin species diversity has been a subject of debate over the past two decades, particularly after the naming of Australopithecus bahrelghazali and Kenyanthropus platyops in addition to the well-known species Australopithecus afarensis. Further analyses continue to support the proposal that several hominin species co-existed during this time period. Here we recognize a new hominin species (Australopithecus deyiremeda sp. nov.) from 3.3–3.5-million-year-old deposits in the…

Another Middle Pliocene hominin, Australopithecus deyiremida, is described, which lived in Ethiopia at around the same time as Australipithecus afarensis ('Lucy') and other species such as Kenyanthropus platyops in Kenya and its morphology suggests that some dental features traditionally associated with later genera such as Paranthropus and Homo emerged earlier than previously thought.

A closer look at the currently available fossil evidence from Ethiopia, Kenya, and Chad indicates that Australopithecus afarensis was not the only hominin species during the middle Pliocene, and that there were other species clearly distinguishable from it by their locomotor adaptation and diet.

It is shown that both hominins and some papionins expanded their diets to include C4 resources as early as 3.76 Ma, which indicates that the inclusion of C4 foods in hominin diet occurred as part of broader ecological changes in African primate communities.

New fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for the understanding of Plio–Pleistocene hom inin phylogeny.

Careful evaluation of the material has led to the recognition of a distinctive suite of morphological traits distinguishing the Laetolil and Hadar remains from other hominid taxa, indicating the necessity of assigning these fossils to a new and more primitive species of Australopithecus.

The results of statistical analyses show that the attribution of KNM-WT 40000 to a separate species and the notion that hominin taxonomic diversity in Africa extends back well into the Middle Pliocene are supported.
