The firm reason for Neanderthals extinction By Ahmad Shammazadeh We know the great populations of Neanderthals during some hundred thousands of years had scattered on many parts of Earth, then between 12000 and 11000 years ago, suddenly disappeared from the planet!! This subject has engaged the minds of many paleontologists, anthropologists and other researchers who looking for a logic and acceptable reason for Neanderthals extinction, but none of them could obtain such important reason yet. Some of them, like as prof. Pat Shipman has delivered some funny ideas and point of views as a reason for the extinction, and others in different ways. Note: why so much of anthropologists have couldn’t find the reason of this basic event yet? The answer may be so: All of them looking for the reason among their knowledge and experiences limited in the frame of Anthropology. If they could break down the anthropology’s shell settled around themselves and put their steps in another scientific fields, and glance at other discoveries, may be they would reach to their goals. I have followed this mysterious event since 1980. Then I have finished my first research on anthropology on 1987. My article published in a Persian scientific magazine after 11 years. By this research which based on some religious and scientific sources, I was sure that the event has not occurred in according to natural conditions; but an especial divine providence has been behind this mysterious event. Afterwards I was looking for a scientific reason for the divine providence. Finally on 2005 I found the reason and reached to my goal, by reading an article on “meteorology and changing the climate of Earth”, released by prof. Farhanieh in a newspaper in Persian on 2001. I used this research as a firm reason for Neanderthals extinction in my article.
