The ancestors of Aboriginal Australians may have reached Australia 18,000 years earlier than originally thought, according to research published in the journal Nature on Wednesday.

Our understanding of the story of humanity’s early migration across the world is being constantly updated with new findings. Now, more sophisticated dating techniques of sediments at a known site called Madjedbebe – home to the earliest evidence of humans in Australia – confirms it is one of the most significant archaeological sites in the world and much older than previously thought.

The below video by National Geographic shows how Aboriginal Australians most likely traveled to the continent by sea, or possibly walked from Papua New Guinea when sea levels were lower.
