probably the most oldest and most complete skeletons of humankind’s ancestors has been unveiled in South Africa.
A group spent more than two decades excavating, cleaning and striking collectively the skeleton of Little Foot.
Its exact age is debated, however South African scientists say the remains are 3.Sixty seven million years ancient.
This is able to mean Little Foot used to be alive about 500,000 years earlier than Lucy, the noted skeleton of an historical human relative determined in Ethiopia.
Both Little Foot and Lucy belong to the equal genus – Australopithecus – but they are distinctive species.
Scientists believe this suggests humankind’s ancestors had been spread throughout a some distance wider field of Africa than had beforehand concept. It additionally suggests there were a various number of species.
Little Foot was found out within the Sterkfontein caves, north-west of South Africa’s principal metropolis Johannesburg, with the aid of Professor Ron Clarke.
It’s thought that she used to be a younger lady who fell down a shaft of one of the vital caves.
“It probably small, but it might be very fundamental. Due to the fact that is how it began, with one little bone. And it helps us to recognize our origins,” Prof Clarke mentioned.
The system of taking out the bones from the caves was painstaking, as the fossil had “very fragile bones”, which have been “totally gentle” and “buried in a usual concrete-like fabric”, he introduced.
“We used very small tools, like needles to excavate it. That’s why it took so long. It used to be like excavating a fluffy pastry out of concrete,” Prof Clarke mentioned.
Analysis: A treasure trove

the full skeleton of Little Foot, as she is known, proves that she is more like us than an ape, with shorter palms and small fingers. She usually slept in trees.
Quite how she fits into our loved ones tree continues to be a work in progress. But she is older than Lucy, a more famous but incomplete skeleton observed in a long way-away Ethiopia.
And that implies our old ancestors had been close to definitely scattered throughout Africa.
Scientists are used to basing their theories on tiny fossil fragments, however South Africa’s caves are quick fitting a treasure trove, and serving to to rewrite our understanding of how our species evolved.
