It is curious how there seems to be an instinctive disgust in Man for his nearest ancestors and relations. If only Darwin could conscientiously have traced man back to the Elephant or the Lion or the Antelope, how much ridicule and prejudice would have been spared to the doctrine of Evolution.
Lions are born knowing they are predators.
Antelopes understand they are the prey. Humans are one of the few creatures on Earth given the choice.
A man from a primitive culture who sees an automobile might guess that it was powered by the wind or by an antelope hidden under the car, but when he opens up the hood and sees the engine he immediately realizes that it was designed.
