The ancient hominin Australopithecus anamensis is thought to be one of our oldest known relations – but what do we actually know about the species? How long ago did they live?

Ardipithecus ramidus is a human ancestor that lived nearly 4.4 million years ago. Our understanding of it is predominantly linked to a partial skeleton found in 2009, nicknamed 'Ardi.' ...

A direct ancestor of Australopithecines was Australopithecus anamensis, a species that lived about 4.2 to 3.9 million years ago. Australopithecus anamensis is significant because it provides a link ...

Fossil hunters have found remains of a probable direct ancestor of humans that lived more than four million years ago. The specimens of this ancient creature are helping bridge a long gap during a ...

Ardipithecus kaddaba 于 1997 年在埃塞俄比亚首次被发现。 下颌骨被发现不属于任何其他已知物种。 很快，古人类学家从同一物种的五个不同个体中发现了其他几块化石。 通过检查部分手臂骨、手骨和足骨、锁骨和脚趾骨，确定这个新发现的物种用两条腿直立行走。

Motivation from the study had originally come from the unique success of both teams in recovering fossils from ancient time horizons, their most celebrated discoveries being the ~4.5-million-year-old ...

Tennessee (US): Many have a doubt that how walking was invented, this is an important question because many anthropologists see bipedalism – which means walking on two legs – as one of the defining ...

The others in the list are orrorin tugenensis, ardipithecus kadabba, ardipithecus ramidus, australopithecus anamensis and homo sapiens etc. Where does the new "Dragon Man" species fit in?

The oldest species found so far on the human evolutionary tree had a 3.8 million-year-old skull found in Ethiopia. It belongs to Austropithecus anamensis, a direct ancestor of the famous “Lucy” ...

One of the most hotly debated issues in current human origins research focuses on how the 4.4 million-year-old African species Ardipithecus ramidus is related to the human lineage.

If that is the case, then we need to revise the human evolutionary timeline, with A. anamensis existing from 4.2m to 3.8m years ago, and A. afarensis from 3.9m to 3m years ago.
