WASHINGTON . A jaw with teeth 2.8 million years, found in Ethiopia is the fossil oldest genus “Homo” found so far. Further, the finding back 400,000 years watch our species, s ccording indicates the journal Science.
This discovery, announced Wednesday in you digital edition of the magazine sheds light on the origin of the genus “Homo”, to which the human species belongs.
“The era of dating the lower jaw reduces the gap in development between Australopithecus, the famous Lucy that dates back 3.2 million years, and the first type species “Homo” as habilis erectus or “explain the paleontologists in the study.
” This fossil is a excellent example of a transitional species in a key period of human evolution, “he added.
The mandible was found in 2013 in an area called tracking Ledi-Geraru in the Afar region of Ethiopia by an international team of researchers, led by Kaye Reed of the University of Arizona (USA .) and Brian Villmoare, University of Nevada (USA.).
For decades, scientists look for fossil in Africa to find clues to the origins of the line “Homo” albeit with limited success as they found very few fossil ago period from three million to 2.5 million years.
“The fossil of “Homo” line of more than two million years are very rare and having a clarification on the early stages of the evolution of our line is particularly exciting, “says Brian Villmoare, lead author of article.
However, researchers say they are unable to say with this one jaw if it is or not a new subspecies within type “Homo”.
