Researchers have unearthed tooth fossils in Ethiopia dating to about 2.65 million years ago of a previously unknown species in the human evolutionary lineage, one that lived in the same time and place as the earliest-known member of the genus Homo to which our own species belongs.

Addis Ababa

A team of scientists has uncovered ten fossilized teeth in Ethiopia's Afar region, estimated to be between 2.6 and 2.8 million years old. The teeth are believed to belong to a new species of early human, shedding light on a little-understood period in human evolutionary history.

The discovery indicates that there was more diversity among early human ancestors than previously thought, with the possibility that multiple species of Australopithecus co-existed alongside early Homo species. Researchers emphasize the need for additional fossils to confirm the classification and gain a clearer understanding of the species' full morphology. Ethiopia continues to be a significant site for paleoanthropological discoveries, including the famous remains of Lucy and Ardi.

Ethiopian fossils shed light on ancestors

They may seem like just a few small teeth, but these fossils open up a whole new chapter in the story of our evolution. Dated between 2.6 and 2.8 million years, scientists concluded that these ten teeth, discovered in Ethiopia's Afar region, belonged to a new species of early human shedding light on a poorly understood period in humanity's history. What makes it special and new is the exciting discovery that there is more diversity in the human lineage, in our origin, in our ancestry than we originally thought at this particular time. The biggest excitement is around the fact that there's more than just one or two or possibly even three species of Australopithecus here in eastern Africa. The close age of the teeth suggests that this newly identified Australopithecus species co-existed in this region with early Homo species, raising questions about whether they competed for the same resources. They are determined to belong to two individuals, however the team which discovered them say more fossils are needed to determine which specific species they belong to. We want to be a little bit cautious about naming it until we have a better picture of all of the morphology, of how its whole body looked, not just five teeth or ten teeth in its mouth, but how did its whole body look, how did its skull look. Ethiopia is also home to several crucial paleo-anthropological discoveries, including the remains of Lucian Ardi, early hominins thought to be humanity's oldest known ancestors.
