4. Genetic Errors
Errors in the genetic code or "gene recipe" can happen in a variety of ways.

Codes have too much information
Information is in the wrong order
Examples

5. Genes and Natural Selection
Natural Selection: a process resulting in the survival of those individuals from a population of animals or plants that are best adapted to the prevailing environmental conditions.
The survivors produce more offspring than those less well adapted  characteristics of the population change over time  evolution
