Scientists have named new species that may have been the direct ancestors of modern humans.
Newly proposed species, Homobodoensis Living in Africa over 500,000 years ago — may help elucidate how human pedigrees migrated and interacted around the world.
I’m a modern person Homo sapiens, The only human pedigree that survived, other human species once roamed the globe.For example, scientists recently discovered that the Indonesian island of Flores was once the home of an extinct species. Homoflores ensis, Often known as the “Hobbit” because of its miniature body.
Determining whether an ancient set of human fossils belongs to one species or another is often a challenging issue open to heated debate.For example, some researchers are with modern humans Neanderthals It means they were different species. However, other scientists consider Neanderthals to be a single species due to the recent abundant genetic evidence that modern humans and Neanderthals once mated and had fertile and viable offspring. I insist that it should not be.
In a new study, researchers analyzed human fossils about 774,000 to 129000 years ago (formerly known as the Middle Pleistocene and now renamed Chibanian). Previous studies have suggested that while Neanderthals emerged in Eurasia, modern humans occurred in Africa during this period. But much of this important chapter in human evolution remains poorly understood — a problem that paleoanthropologists call “middle turmoil”.
Chibanian human fossils from Africa and Eurasia are often assigned to one of two species: Homo heidelbergensis Also Homo rhodesiensis.. However, both species often had multiple, and often contradictory definitions of skeletal features and other features that describe them.
recently DNA Evidence revealed that some European fossils were dubbed H. Heidelbergensis It was actually from the early Neanderthals. like that, H. Heidelbergensis Scientists said it was a verbose name in such cases.
Similarly, recent analysis of many East Asian fossils suggests that they should no longer be called. H. Heidelbergensis, The researchers added. For example, many of the faces and other features found in human fossils of Chibanian East Asia differ from those found in fossils of Europe and Africa of the same age.
In addition, Chibanian fossils from Africa are sometimes called both. H. Heidelbergensis When H. rhodesiensis.. Scientists also H. rhodesiensis It was a poorly defined label that was not widely accepted in science, partly due to its relationship with the controversial British imperialist Cecil Rhodes.
To help deal with all this confusion, researchers are now proposing the existence of a new species, H. bodoensisNamed after a 600,000-year-old skull discovered in Baudard, Ethiopia in 1976. This new name includes many fossils that were previously identified as either. H. Heidelbergensis Also H. rhodesiensis..Researchers H. bodoensis Was a direct ancestor of H. sapiensThe fossils of Siberia and Tibet formed branches of a human pedigree that differed from those that produced the Neanderthals and the mysterious Denisovans together, and that they lived at about the same time as their Neanderthals’ cousins. Suggested.
“Giving a new name to a species is always controversial,” said Miljana Roxandick, a paleoanthropologist and co-lead author of the study at the University of Winnipeg, Canada. “But if people start using it, it will survive and stay alive.”
In this new classification H. bodoensis Describes most Chibanian human fossils from Africa and the eastern Mediterranean. Many Chibanian human fossils from Europe will be reclassified as Neanderthals.Name H. Heidelbergensis When H. rhodesiensis Then it disappears. Chibanian human fossils from East Asia may get their own name in more research.
“We do not claim to rewrite human evolution,” Roxandick said. Instead, researchers are trying to organize the changes seen in ancient humans “in a way that allows us to discuss where it comes from and what it represents.” “These differences help us understand movements and interactions.”
In the future, researchers want to see if they can find something H. bodoensis A European specimen from the Chibanian, Roksandic, said.
Scientists detailed their findings in the journal online Thursday (October 28) Evolutionary Anthropology: Publish News and Reviews..
