Humanity vs Super Intelligent Crows
The Great Crow magically gives all crows in the world a boost in their intelligence to have an average IQ of 140. The crows are also given mild telekinesis within a distance of a meter with the crow's own strength to simulate opposable thumbs. Man is not notified that there is now a hyper intelligent species of crow, though they may start figuring it out based upon the behavior of the crows. Any crow offspring will also have the super intelligence and telekinesis. Due to the limits of her powers, the Great Crow tells all of the crows that they must become the dominant species upon the Earth (either subjugating or eliminating most of humanity) within 20 years, and if not, they will lose their intelligence. The Great Crow does not possess any special powers beyond that one time miracle of gifting crows enlightenment. Assuming humanity doesn't make any meaningful technological advances in this time, who will win? All of man or all of crow?
