Darwin's Four Postulates
Rodrigo Segovia
Evolution and Natural Selection
1. Variation within species- Species differ and have different variations between them.
2. Variation is heritable- DNA and heritage is what makes people get traits. And some may be advantageous and some may be disadvantageous.
3. Overproduction- Species have to produce more of the young in order to survive.
4. Non-random survival- This is the main idea of Natural Selection, that survival is not random but it is by natural selection for the evolution of the species.
