Darwin's Four Postulates
Alvin Methoth
Origin of Species
1. Variation
Organisms inside a population show individual variations in their appearances and their behaviors. Some traits that can be part of variation include; body size, hair color, facial markings, voice properties, offspring number.
2. Inheritance
Traits that are consistently passed on from generation to generation, from parent to offspring. These traits are heritable and mostly consistent.
3. High Rate of Population Growth
In every generation, more offspring are produced than can survive due to limited resources. This resource scarcity leads to a struggle for existence.
4. SURVIVAL OF THE FITTEST
