Scientists said that the discovery of new fossils belonging to “Australopithecus sediba” settled a decades-old debate about how hominins moved millions of years ago.
According to the British newspaper, “Daily Mail”, an international team of researchers, led by New York University and the University of the Witwatersrand in Johannesburg analyzed bones found in rock masses inside a cave in South Africa.
These bones, which have been described as the “missing link”, belong to the lower back.
And the “Daily Mail” explained that the researchers used these bones to reconstruct “Australopithecus sediba”, which is… primitive human ancestor.
The “missing link” revealed that this species was walking and also used its upper limbs to climb, like monkeys.
Professor Scott Williams, principal investigator at New York University, said the lumbar region is important for understanding walking in our early ancestors.
