Mammals are one largest species of animals on earth and they are closely related to Man.

Mammals are animals that can give birth to their young ones alive just like a human being and also they have mammary glands..

Yes, there are mammals that have larger brain than human.

But let's not confuse size for quality because size is not everything..

According to experts, the largest brain in the world belongs to the sperm whale.

The adult sperm whale has a brain of 8000 cubic centimeters while the human brain is 1300 cubic centimeters .

But this doesn't mean they are more intelligent than human being in any way..

Firstly, human being is superior to any animals on earth and when God created the Earth and everything in it,he put man in charge and in control of everything he created and all his resources including all the animals.

The fact that the whale has the largest brain doesn't mean he is better it's just a matter of size just like an engine displacement.

Compare the space in the cylinder of a bettle car and that of a two and half formula one race car.
