Term
| Evolution by natural selection |

| The Darwinian theory that evolution proceeds by differential success in reproduction |
|
|
Term
| Four main observations and Single inference of Charles Darwin in On The Origin Of Species By Means Of Natural Selection |
|
Definition
1.Reproduction will tend to increase a population rapidly unless factors limit it.
2. Individuals of a given species are not identical.
3. Some of the variation among individuals is inherited.
4. Not all offspring of a given generation will survive to reproduce.
Inference: Variation among individuals affects the probability of their surviving. |
