According to Arch. News(1.11.2018) which quoting from the Science News says that Saudi Arabia’s Ti’s al Ghadah site was capable of supporting life between 500,000 and 300,000 years ago.

Study of fossils of antelopes, elephants, and other animals of this site is fraught with danger of academic preaching of wrong things on history of human civilization; it is more dangerous when a scholars try to prove that ‘early humans would not have had to adapt to harsh conditions in order to cross the Arabian Peninsula after leaving Africa’. What difference it will make if scholars reduce ‘500,000 and 300,000 years ago’ tag to Ti’s al Ghadah site supporting life to 1000 years ago?
