Australopithecus afarensis is normally regarded as being an immediate ancestor of people. Additionally, it is regarded as being an ancestor that is direct of types of Australopithecus and all sorts of types within the Paranthropus genus.
The names Praeanthropus africanus and Praeanthropus afarensis have now been recommended as alternatives by researchers whom think this species doesn’t belong into the genus Australopithecus.
In 2015, a group under Yohannes Haile-Selassie described when you look at the journal Nature a brand new types A. Deyiremeda (through the Afar language, deyi meaning ‘close’ and remeda meaning ‘relative’). The fossils date to 3.5 to 3.3 million yrs. Old and had been found in Woranso-Mille in Ethiopia, near to sites of the age that is similar produced A. Afarensis specimens. If correct, A. Afarensis had not been the hominin that is only in eastern Africa at the moment.
The fossils, all present in March 2011, add a partial upper jaw bone tissue (holotype BRT-VP-3/1), two reduced jaws (paratypes BRT-VP-3/14 and WYT-VP-2/10) and an separated P4 tooth in a maxillary fragment (referred specimen BRT-VP-3/37). Key features included forward cheek bones, three-rooted premolars and tiny crowns that are first-molar. Evaluations had been created using other known center Pliocene hominins such as Kenyanthropus platyops and A. Afarensis; the discovers thought there have been sufficient differences to justify a species designation that is new. Others disagree, claiming that making evaluations with K. Platyops is problematic (the only skull ended up being extremely distorted and perchance badly reconstructed) or that the little test dimensions are maybe not adequate to draw such major conclusions.
