An ancient, 3-foot-tall human, whose unusually small stature has earned it the moniker “hobbit”, has astounded evolutionary researchers since it’s bones were discovered on the island of Flores, in Indonesia. Some scientists have proposed that the individual was a Homo sapien with a growth disorder.
Recently discovered teeth from the hobbit propose it is a unique species, as opposed to a present-day human with a development issue. The new research also proposes that hobbits may share a immediate ancestor with present-day humans.
The 18,000-year-old fossil remains of the hobbit were found in 2003. From that point forward, scientists have suggested that the hobbit, which had a brain about the size of a grapefruit, was a branch of the human lineage Homo, named Homo floresiensis. On the other hand, separate scientists have contended that the hobbit was truly a current human with microcephaly, a condition that leads to an abnormally little head, a little body and some mental impediment.
To learn more about the hobbit, researchers have now performed the first comprehensive investigation of the ancient human’s teeth. The analysts contrasted the 40 known hobbit teeth and those from 490 present-day people from Asia, Oceania, Africa and Europe, as well as from an assortment of extinct hominins, such as Homo habilis.
The scientists discovered that hobbit teeth were as small as those from short present-day humans. On the other hand, different features of these teeth looked totally divergent from those of present-day humans.
The hobbit teeth showed an exceptional mosaic of primitive attributes seen in early hominins blended with more-propelled characteristics displayed by later hominins, the scientists said. For example, the canine and premolar teeth looked primitive, while the molar teeth looked advanced, or as though they had emerged later in the evolution of Homo sapiens.
These discoveries negate prior assertions that hobbits had teeth completely like those of modern humans. The outcomes likewise propose that hobbits were not simply modern humans with serious abnormalities, the scientists said.
While human ancestry, for the most part, developed bigger bodies and brains through time, the hobbit suggests that seclusion on islands could considerably switch this developmental pattern, Yousuke Kaifu, a paleoanthropologist at Japan’s National Museum of Nature and Science, Tokyo, said.
The scientists detailed their discoveries November 18 in the online journal PLOS ONE.
