Man is the most intelligent mammal God ever created.
Although we are far from being perfect and have done many cruel things to each other as well as to the planet, one cannot deny some of the of the major accomplishments that have been made from air travel, landing on the moon, phones/cell phones, cars, boats, radio, television, incredible buildings, air conditioning, heating...etc
What other mammal can (control) the temperature of it's dwelling?
I had an instructor once tell our class: Intelligence is the ability of an organism to adapt to it's enviorment. Man clearly has done that with the earth. To many in dismay man has actually (changed) the earth.
