Key Questions:

1. How can variation lead to natural selection?
   • the variation between species and between individuals of the same species meaning some organisms compete more successfully, which can drive natural selection
2. Despite belonging to the same species, individuals often are different. What is this difference called and what two forms can it grouped into?
   • the variation between individuals within a species being continuous or discontinuous, to include measurement and graphical representation of variation
3. What is the definition of a species?
   • A species is defined as a group of organisms who's genetic information is compatible such that their offspring can also reproduce.
4. What is continuous variation?
   • The variation between individuals within a species being continuous when there are (near) infinite number of possibilities. Continuous variation is often measureable and with units.
5. What is discontinuous variation?
   • Discontinuous variation is often described by words or integers. The variation between individuals within a species being discontinuous when fits into a distinct category
6. How would a graph of discontinuous variation and continuous variation be different?
   • Discontinuous would be a bar graph of categories and their frequency. Continuous would be a histogram of artificially made groups and their frequency.
