HARROW: According to the findings of a new study, a fossil discovery has made a notable addition to new facts related to the evolutionary tree of humans. The study has revealed that a new species of humans probably lived alongside the ‘Lucy’ species. The study is based on the discovery of a lower jaw, teeth and jaw fragments in north Ethiopia’s Afar region four years back. The fossil was believed to be 3.3 million to 3.5 million years old.
According to researchers of the study, the second species of humans lived in the same time and area as the species, Lucy. The study has been published in the journal Nature. The researchers have assigned the new study to a species that they named ‘Australopithecus deyiremeda’.
Yohannes Haile-Selassie, researcher from the Cleveland Museum of Natural History and lead author of the study, said that the study has linked new fossil to our branch of family tree, but the researchers don’t know how it is related.
Human branch of family tree, which includes human species like Homo sapiens and some of our closest extinct relatives, arose from the evolutionary grouping that now includes new species and Lucy’s species. Haile-Selassie said that the new creatures have made it difficult to identify which species led to our branch.
