An increase in global water temperatures of only 2°F could raise the ocean level by two feet; melting ice caps could creating extreme flooding and changing the face of the landscape the world over…Low-lying cities, such as New York and New Orleans, would be the first to be affected.

Evolution is badly misunderstood by the vast majority of people. This week a fossil discovery seems to have confirmed what evolutionary biologists have been saying for years. But, it isn’t the “missing link” any more than Piltdown Man.
