Raven Defies Natural Selection
National Geographic presents an experiment in which a raven is put on a branch while its food is hung from a string. Researchers wanted to see if the raven could think through the process and pull the string up to itself to obtain the food.
The problem is that:
1) The behavior was not learned as the researchers did not teach the raven the skill
2) Natural Selection does not provide the answer as the scenario would not have occurred in the wild
3) Chance could not provide the answer because there were too many individual steps
Thus, the ability to actively think through solving this problem must be an innate quality. But for a bird without a cerebral cortex - instrumental in creative thought - to perform such a function is nothing short of magical.
