Remains of this species date back to 1.8 million to 300,000 years ago. This cave near Shanidar, northern Iraq, was inhabited by humans for almost 100,000 years. The brain size in the Hominid lineage from Australopithecus to Homo increased dramatically from about 500 to 1350 cubic centimeters. Biological Evolution and Linguistic Diversification Diversification of languages parallels strikingly the evolutionary process, although the underlying processes are different. Languages, like new species, arose in isolation accumulating more and more differences over time.
