The Levantine Corridor Is Interpreted to Have Been

The Levantine Corridor is interpreted to have been:

A) the route taken by Homo erectus from continental Asia to the islands of the western Pacific
B) the anatomical location on the interior of the skulls of advanced hominins where the two hemispheres of the brain are connected by a bundle of nerves; the "corridor" is not seen in the crania of apes
C) a broad and deep valley whose existence in central India may explain why handaxe technology is not seen to the east in China
D) a natural passageway likely followed by Homo erectus as they expanded beyond Africa into west Asia.
