The Effect of Existence of Neanderthals' DNA
We, the modern men, inherited some DNA from Neanderthals, a different type of human beings than the current ones. About 45,000 to 40,000 years ago, our ancestors exited from Africa and met Neanderthals. It resulted in inclusion of Neanderthals' DNA in our DNA at about 2%.
Genetic research has asserted that some admixture took place.[190] The genomes of all non-Africans include portions that are of Neanderthal origin,[191][192] due to interbreeding between Neanderthals and the ancestors of Eurasians in Northern Africa or the Middle East prior to their spread. Rather than absorption of the Neanderthal population, this gene flow appears to have been of limited duration and limited extent. An estimated 1.5 to 2.1 percent[36] of the DNA in Europeans and Asians (French, Chinese and Papua probands) is non-modern, and shared with ancient Neanderthal DNA. This DNA is absent in Sub-Saharan Africans (Yoruba people and San probands).[88] Ötzi the iceman, Europe's oldest preserved mummy, was found to possess an even higher percentage of Neanderthal ancestry.[193] The two percent of Neanderthal DNA that lives on in Europeans and Asians is not the same in all Europeans and Asians: In all, approximately 20% of the Neanderthal genome appears to survive in the modern human gene pool.The most important fact is that our ancestors met and interbred with Neanderthals in the Middle East before they traveled and expanded to all over Europe, Asia, and Pacific.

Although all the major religions were generated around the Middle East, the effect of existence of Neanderthals' DNA in the modern human beings on generation of the major human religions is not clear. But the concept of God might have emerged in the human mind due to the effect of existence of Neanderthals' DNA.
Or the idea of the communication between the human mind and the God might reflect the communication between our ancestors and Neanderthals, because two types of the mankind had been separated for more than 200,000 years but could communicate with each other beyond some gap over some difficulties.
(Nonetheless, there is a possibility that Neanderthals' DNA in the modern human beings might have negative influence on behaviors of modern men outside Africa in terms of violence and insanity.)
