One of the oldest and maximum entire skeletons of humankind's ancestors has been unveiled in south africa.
A team spent more than two decades excavating, cleaning and setting together the skeleton of little foot.
Its genuine age is debated, but south african scientists say the stays are 3.67 million years vintage.
This will suggest little foot turned into alive approximately 500,000 years before lucy, the famous skeleton of an historical human relative found in ethiopia.
Both little foot and lucy belong to the identical genus - australopithecus - but they may be special species.
Scientists consider this shows humankind's ancestors had been spread throughout a miles wider location of africa than had formerly idea. It also suggests there were a diverse range of species.

Little foot was determined inside the sterkfontein caves, north-west of south africa's foremost city johannesburg
It's miles concept that she turned into a young lady who fell down a shaft of one of the caves.
"it might be small, however it is probably very critical. Because it truly is how it started, with one little bone. And it helps us to apprehend our origins," the group chief, professor ron clarke, said.
The technique of removing the bones from the caves became painstaking, as the fossil had "very fragile bones", which have been "extremely soft" and "buried in a herbal concrete-like fabric", he delivered.
"we used very small equipment, like needles to excavate it. It really is why it took goodbye. It turned into like excavating a fluffy pastry out of concrete," prof clarke stated.
Evaluation: a treasure trove

The whole skeleton of little foot, as she is thought, proves that she is greater like us than an ape, with shorter arms and small hands. She in all likelihood slept in trees.
Quite how she fits into our own family tree continues to be a piece in development. However she is older than lucy, a greater well-known but incomplete skeleton observed in a ways-away ethiopia.
And meaning our historical ancestors had been almost without a doubt scattered across africa.
Scientists are used to basing their theories on tiny fossil fragments, but south africa's caves are fast turning into a treasure trove, and helping to rewrite our knowledge of the way our species advanced.
