There are some mammals that are considered to be stronger and more dominant than the others. They normally show their dominance by acting as leaders. This can be very particular in some groups of mammals. Human beings are a perfect example of this. In the world that we are living in right now, in groups, in families, and in other aspects of society, there will always be leaders.
These leaders will show their dominance by showing that they need to be followed. They will have the power to make people become submissive and follow them. Aside from humans, this type of behavior can also be seen in certain types of monkeys like baboons.
