The homo sapien-homo neanderthalic hybrids civilization conquered the world and became the dominant species on the earth. The homo neanderthalic species had a small frontal cortex and a dominant cerebellum resulting in epidemic autism in the species. The homo neanderthalic species being autistic were not capable of creative fictional imagination and myth formation. This resulted in the homo neanderthalic species being grouped as small colonies and did not evolved into nation-states and civilizations. The homo neanderthalic species were overtaken by the homo sapien-homo neanderthalic hybrids and gradually became extinct except in few pockets of the world. The Shudras of India, the Jews of Israel, Muslims of Middle-East, the Celts of Europe, Australian Aboriginals, Maoris and the Native South American Indians. The homo sapien-homo neanderthalic hybrids of Europe and Eurasia were the Aryan population. This can be deciphered from the population behaviour. The Nazi mediated holocaust of Jews, the Islamophobia in Europe and upper caste Indians and the racial discrimination as denoted by the caste system against the Shudras in India are examples of it.
