- Problems with classification
- Some hybrids are fertile
- Two closely related species can sonmetimes interbreed
- Some organisms reproduce asexually
- Ring species
- Begin as a single population of a species
- As the species' range expands, ecological
barriers can seperate sub-populations
- These populations can spread and become isolated again
- Eventually, a chain of populations is formed
- Each population differs from the last
- The populations at either end of the chain may be so
different that they could be classified as a new species
- Species
- Can produce fertile offspring
- How are organisms classified
