One hundred years ago, a paper was published in the journal Nature that would radically shift our understandings of the origins of humanity. It described a fossil, found in a lime mine in Taung in South Africa, which became known as the Taung child skull.
The paper’s author, an Australian-born anatomist called Raymond Dart, argued that the fossil was a new species of hominin called Australopithecus africanus. It was the first evidence that humanity originated in Africa.
In this episode of The Conversation Weekly podcast, we talk to science historian Christa Kuljian about Dart’s complicated legacy and to paleoanthropologist Dipuo Kgotleng about what’s happened to the city of Taung itself, and how paleoanthropology has changed over the last century.
When Dart’s paper was first published, it was roundly ridiculed by his scientific peers. Charles Darwin had a hunch that all humans had common origins in Africa, but archaeologists at the time weren’t looking for evidence on the continent, as Kuljian, a research associate at the University of Witwatersrand, explains:
“Scientists argued that humans had evolved in Europe or perhaps Asia, and that belief was influenced by the false assumption that many scientists had that Europeans were superior to other people from around the world, and that there was a hierarchy of race. Paleoanthropology and the search for human origins had its roots in that era of racialised thinking and white supremacy.”
Dart’s contribution eventually proved this to be wrong. But at the same time, Dart, like many scientists working in Europe and the US in the early 20th century, was engaged in disturbing and racist anthropological practices, says Kuljian.
“They were not only collecting ancient fossils, they were also collecting human skeletons. And scientists thought that humans could be divided into separate and distinct racial types based on physical characteristics. They thought that these pure racial types, which we now know do not exist, would give them a clue to understanding human evolution.”
Not just one ‘hero’
Alongside Dart’s own complicated legacy, researchers are also reassessing the way discoveries like the Taung child skull are commonly told: through the lens of a solo, white, hero like Indiana Jones.
What’s missing, says Kgotleng, director of the Palaeo Institute at the University of Johannesburg, are often the stories of the “hidden figures” behind such discoveries. For example, the rock that contained the Taung skull was put aside by local mine workers who recognised its potential significance and passed it onto Dart’s colleague. Kgotleng argues:

” For a scientist to have that fossil in hand there was somebody who was on the ground assisting with that excavation. There were other labourers who were there, in most cases they never get recognised … we need to recognise all the workers in that whole process of the discovery through to publication.”
Kgotleng, who used to work as the archaeologist at Taung, says that today the town “generally looks like it’s still stuck in the 1920s”. She says that many local people know little about the significance of the fossil find and that “the knowledge about the science has not filtrated through to the locals”.
Listen to the conversations with Kuljian and Kgotleng on The Conversation Weekly podcast, which also includes an introduction from Natasha Joseph, science commissioning editor at The Conversation Africa. Kuljian and Kgotleng both also contributed papers to a special issue of the South African Journal of Science to mark the centenary of Dart’s article.
