Where Chimpanzees Fail, Crows Succeed
Crows are more innovative than chimpanzees. Image courtesy of Wikipedia.
According to Darwinian evolution, chimpanzees are almost human. They should thus belong to the wisest of animals.
However, when it comes to tasks requiring innovation, crows are much better than chimpanzees.
Recently, researchers at Oxford University noticed that New Caledonian crows were able to use three different tools in the right sequence to get food.
According to a study published in the journal PloS One, the crows first had to use a short tool to get at a longer one. Next, using this, they had to drag the longest tool within reach so that they could get at the food.
Of the seven crows, five were repeatedly able to use the right tools in the right sequence. Four of the birds succeeded on their first attempt.
Chimpanzees have not succeeded in similar tasks. Although animals have some innate intelligence due to creation , there is an insurmountable intellectual chasm between humans and animals.
It seems that when it comes to innovation, crows are closer to people than chimpanzees.
In other words, the crows did bother to comply with the predictions of the Evolution model.
