The Homo erectus in today’s Saudi Arabia were too conservative to survive
An article published in the journal “PLOS ONE” describes a research on a population of Homo erectus which claims that their extinction was partly due to their laziness. A team coordinated by the Australian National University (ANU) excavated in Saffaqah, near Dawadmi, in central Saudi Arabia, examined remains belonging to the acheulean culture of the Lower Paleolithic, concluding that in the collection of resources and in the production of tools, local Homo erectus used minimal effort strategies with poor adaptability that could have been fatal in the long run.
