A finger bone is pointing to what scientists are calling a new understanding of how ancient human beings came out of Africa and began settling the rest of the world. The middle bone of an adult’s middle finger were unearthed in the Nefud Desert of Saudi Arabia. It was found in an area called Al Wusta. Testing has dated the fossilized remains to about 90,000 years ago. Researchers reported that it is the oldest Homo sapiens fossil ever found outside of Africa and the eastern Mediterranean Levant area. They also said it is the first human fossil from the Arabian peninsula. While the Nefud Desert is now a sea of sand, it was green when this Homo sapiens lived. The researchers say the area was once a grasslands, filled with wildlife, near a freshwater lake.
