Long article, with lots of links, so I'll copy only the first paragraphs and you'll click the link if interested:
Archaeological discoveries are happening faster than ever before, helping refine the human story

In 1924, a 3-year-old child’s skull found in South Africa forever changed how people think about human origins.

The Taung Child, our first encounter with an ancient group of proto-humans or hominins called australopithecines, was a turning point in the study of human evolution. This discovery shifted the focus of human origins research from Europe and Asia onto Africa, setting the stage for the last century of research on the continent and into its “Cradles of Humankind.”

Few people back then would’ve been able to predict what scientists know about evolution today, and now the pace of discovery is faster than ever. Even since the turn of the 21st century, human origins textbooks have been rewritten over and over again. Just 20 years ago, no one could have imagined what scientists know two decades later about humanity’s deep past, let alone how much knowledge could be extracted from a thimble of dirt, a scrape of dental plaque or satellites in space.
