Un reciente estudio revela que ocurrió al menos 10.000 años antes
Cuándo y cómo llegaron los primeros humanos a Australia es algo que ha sido objeto de debate durante décadas. Si bien se acepta que los seres humanos aparecieron en África hace unos 200.000 años, los científicos han llevado cada vez más atrás en el tiempo, la llegada a Australia. Ahora, un equipo de expertos de la Universidad de Washington, ha encontrado y fechado artefactos en el norte de la isla que indican que los seres humanos llegaron hace unos 65.000 años, más de 10.000 años antes de lo que se pensaba.
El artículo, publicado en Nature, describe técnicas de datación y hallazgos de artefactos en Madjedbebe, un sitio arqueológico, que podría aportar nueva información sobre los primeros seres humanos y su coexistencia con la vida silvestre en el continente australiano. La fecha tiene una gran relevancia en otro contexto ya que cuestiona el argumento de que los humanos causaron la extinción de la megafauna única de Australia, como los canguros gigantes, wombats y tortugas.

When and how the first humans made their way to Australia has been an evolving story.
While it is accepted that humans appeared in Africa some 200,000 years ago, scientists in recent years have placed the approximate date of human settlement in Australia further and further back in time, as part of ongoing questions about the timing, the routes and the means of migration out of Africa.
Now, a team of researchers, including a faculty member and seven students from the University of Washington, has found and dated artifacts in northern Australia that indicate humans arrived there about 65,000 years ago — more than 10,000 years earlier than previously thought. A paper published July 20 in the journal Nature describes dating techniques and artifact finds at Madjedbebe,...

Archaeological excavations at a site near Kakadu National Park have pushed back the date of human arrival in Australia by up to 18,000 years. So how did scientists come up with that date?
Located in Mirarr Country, 300 kilometres east of Darwin, the Madjedbebe rock shelter sits at the base of the Arnhem Land escarpment on a sandy plain.
At around 65,000 years old, it is Australia's oldest documented site, according to a new study by a team of Australian scientists in the journal Nature.
The key to establishing the dates of a site like this comes down to the techniques used to excavate and date the site...
