1. Overproduction
ALL animals and humans have an innate desire to reproduce and extend their race
In order to reduce the chances of their death they produce in a large number.
2. Struggle for existence
The individuals grow in such a climate where food and shelter remains the same.
This leads to a struggle for existence among them.
3. Variations

This is called selection of the fittest.
