A New Species lived Alongside ‘Lucy’: Study

A new study suggested that a fossil find could add new evidence in the human evolutionary tree. As per the study, a new species may have lived alongside the 'Lucy' species. About four years ago, a lower jaw, teeth and jaw fragments were discovered in the Afar region of northern Ethiopia. The fossil dated back at 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.

According to Haile-Selassie, "Previously, fossilized foot bones found in 2009 near the new discovery site had indicated the presence of a second species. But those bones were not assigned to any species, and it's not clear whether they belong to the newly identified species either".

Bernard Wood from George Washington University said that the findings of the new study have provided sufficient evidence which showed that a second species lived alongside the Lucy's species. But, the question is how they shred the land at that time, Wood added. Wood wasn't part of the new study.
