Research suggests that ancient “hobbits” living in Indonesia most certainly got here from Africa and weren’t dwarf descendants of early humans.
The bones of a brand new variety of human, after being discovered on the Indonesian island of Flores in 2003, were called “hobbits” attributable to their size.
Until a brand new species, called Homo floresiensis, was discovered, it was thought that our species, Homo sapiens, had been the one remaining species of Homo for over 30,000 years.
Homo floresiensis is understood to have lived on Flores until 54,000 years ago.
They were considered related to the much larger Homo erectus, which lived from 1.9 million years ago to only 35,000 years ago.
They were the one early hominids known to have lived within the region, whose fossils were discovered on the Indonesian continent of Java.
However, probably the most comprehensive study of hobbit bones concerned the situation of the newly discovered species within the human evolutionary tree.
The findings suggest that it was most certainly a sister species to Homo habilis, one in all the earliest known human species present in Africa 1.75 million years ago.
The Australian National University’s findings showed there was no evidence to support the favored theory that Homo floresiensis evolved from Homo erectus.
Visiting colleague Dr Debbie Argue from the ANU School of Archeology and Anthropology said the outcomes should help end a debate that has been hotly contested for the reason that discovery of Homo floresiensis.
She said: “Analysis shows that on the family tree, Homo floresiensis was probably the sister species to Homo habilis. This signifies that they each had a standard ancestor.
“It’s possible that Homo floresiensis evolved in Africa and emigrated, or a standard ancestor moved out of Africa after which evolved into Homo floresiensis somewhere.”
While previous studies focused mainly on the skull and jaw, the brand new study used 133 data points covering the skull, jaws, teeth, shoulders, legs and arms.
Dr. Argue stated that no data supports the speculation that Homo floresiensis evolved from Homo erectus.
She said: “We checked out whether Homo floresiensis may very well be descended from Homo erectus.
“We found that for those who try to attach them within the family tree, you get a result that has no support. All the tests show that it doesn’t fit – it’s just not a viable theory.”
Dr. Argue said this was supported by the indisputable fact that in lots of respects, resembling jaw structure, Homo floresiensis was more primitive than Homo erectus.
She added: “Logically speaking, it could be obscure how such a regression occurred – why would the Homo erectus jaw evolve back to the primitive state we see in Homo floresiensis?”
Dr Argue said the analyzes also supported the speculation that Homo floresiensis can have branched off earlier, greater than 1.75 million years ago.
“If this were the case, Homo floresiensis would have evolved before the earliest Homo habilis, which would make it very archaic indeed,” she said.
Professor Mike Lee from Flinders University and the South Australian Museum used statistical modeling to investigate the information.
He said: “When we did the evaluation, we got really clear support for a link to Homo habilis. Homo floresiensis occupied a really primitive position on the human evolutionary tree.
“We will be 99 percent sure that it isn’t related to Homo erectus and almost one hundred pc that it isn’t deformed Homo sapiens.”
The study was published within the Journal of Human Evolution.
