Experts Name New Species of Human Ancestors

An international team of researchers, led by Dr. Miljana Roxandick, a paleoanthropologist at the University of Winnipeg, has announced the naming of a new species of human ancestry, Homo bodhensis. This species inhabited Africa in the mid-Pleistocene about 500,000 years ago and was a direct ancestor of modern humans.

The Mid-Pleistocene (now renamed Chibanian, dated 774,000-129,000 years ago) is our own species in Africa (Homo sapiens), our closest relatives, Neanderthals in Europe. It is important because I saw the rise of (Homo neanderthalensis).

However, Human evolution This era is not well understood and is a problem that paleoanthropologists call “middle turmoil.” The announcement of Homo bodoensis hopes to bring some clarity to this mysterious but important chapter in human evolution.

The new name is now based on a reassessment of existing fossils from Africa and Eurasia period.. Traditionally, these fossils have been variously assigned to either Homo heidelbergensis or Homo rhodesiensis, both of which had multiple, often contradictory definitions.

According to the lead author of the study, Roksandic, “talking about human evolution during this period was impossible due to the lack of proper terminology to recognize human geographic variation.”

Recently, the evidence of DNA is H. Some European fossils, called heidelbergensis, are actually early Neanderthals, indicating that their names are redundant. For the same reason, according to co-author Xiu-Jie Wu (Institute of Vertebrate Paleontology and Paleoanthropology, Beijing, China), the name should be abandoned when describing fossil humans in East Asia.

An African fossil dating back to this time, which further confuses the story, is H. Sometimes referred to as both heidelbergensis and H. rhodesiensis. H. rhodesiensis is not well defined and its name has never been widely accepted. This is partly due to his relationship with Cecil Rhodes and the horrific crimes committed during African colonial rule. This is an unacceptable honor given the important work being done towards the decolonization of science.

The name “bodoensis” comes from the skull found in Bodo D’ar, Ethiopia, and the new species is understood to be a direct ancestor of humans. In the new classification, H. bodoensis describes most of the mid-Pleistocene humans from Africa and some from Southeastern Europe, but many from the latter continent are reclassified as Neanderthals.

Co-lead author Predrag Radovic (University of Belgrade, Serbia) said, “In order to facilitate communication, terms need to be clear in science. If they conflict with fossil records, they should be treated as absolute. Not. “

According to one of the co-authors, Christopher Bee (University of Hawaii, Manoa, Faculty of Anthropology), H. The introduction of bodoensis aims to “break the Gordian knot and allow us to clearly communicate this important time in human evolution.” ).

Roksandic agrees that: “The naming of new species is important because the International Animal Naming Commission only allows renaming under very tightly defined rules. It has been around for a long time and the names of new classifications. I’m sure it will survive, only if other researchers use it. “
