NEW DELHI: another human progenitor species which wandered the Afar district of Ethiopia 3.3 to 3.5 million years back has been found by a global group of researchers. Named Australopithecus deyiremeda, this new species joins "Lucy" the celebrated hominin that is known not lived in the same locale. The revelation is portrayed in the science diary Nature.
Lucy's species (called Australopithecus afarensis ) lived from 2.9 million years back to 3.8 million years prior, covering in time with the new species. The new disclosure is the most convincing proof that more than one firmly related human precursor species lived in the same period, more than 3 million years back. The species name "deyiremeda" (day-ihreme-dah) signifies "close relative" in the dialect talked by the Afar individuals, as indicated by the Cleveland Museum of Natural History.
Australopithecus deyiremeda varies from Lucy's species regarding the shape and size of its thick-enameled teeth and the hearty construction modeling of its lower jaws. The front teeth are likewise moderately little demonstrating that it presumably had an alternate eating regimen.
"The new species is yet another affirmation that Lucy's species, Australopithecus afarensis, was by all account not the only potential human predecessor species that wandered in what is currently the Afar district of Ethiopia amid the center Pliocene," said lead creator Dr Yohannes Haile-Selassie of the Cleveland Museum. "Current fossil confirmation from the Woranso-Mille study zone plainly demonstrates that there were no less than two, if not three, early human species living in the meantime and in close geographic closeness."
"This new species from Ethiopia takes the progressing civil argument on right on time hominin assorted qualities to another level," said Haile-Selassie. "Some of our associates will be doubtful about this new species, which is not uncommon. Nonetheless, I think the time it now, time that we investigate the prior periods of our development with a receptive outlook and painstakingly analyze the as of now accessible fossil proof as opposed to quickly rejecting the fossils that don't fit our long-held speculations," said Haile-Selassie.
Researchers have since quite a while ago contended that there was stand out prehuman species at any given time somewhere around 3 and 4 million years prior, consequently offering ascent to another new species through time. This was what the fossil record seemed to demonstrate until the end of the 20th century.
Be that as it may, the naming of Australopithecus bahrelghazali from Chad and Kenyanthropus platyops from Kenya, both from the same time period as Lucy's species, tested this long-held thought. Despite the fact that various specialists were suspicious about the legitimacy of these species, the declaration by Haile-Selassie of the 3.4 million-year-old Burtele halfway foot in 2012 cleared a portion of the distrust on the probability of different early hominin species in the 3 to 4 million-year range.
This revelation has critical ramifications for our comprehension of ahead of schedule hominin environment. It additionally brings up huge issues, for example, how various early hominins living in the meantime and geographic region may have utilized the common scene and accessible assets.
