| Question | Answer |
|---|---|
| evolution | the cumulative changes that occur in a population over time |
| species | a group of interbreeding or potentially interbreeding populations that is reproductively isolated from other such groups |
| genes | the portions of an organism's DNA that carry the code responsible for building that organism in a very specific way |
| survival of the fittest | a popular term that refers to natural selection which is a mechanism that drives evolutionary change |
| How can evolution refine existing adaptations? | One structure of an organism most likely evolved from a simpler version of that structure. The refinement is made over time rather than a giant leap in change. |
| How was chitin modified to serve an additional function? | The chitin of the arthropods started to work as a water loss resistant when the arthropods moved from water to land. |
| How were flippers of penguins modified for a new function? | When penguins started changing their environment to being mostly in water, the flippers eventually changed instead of helping them fly it would help them swim. There's little need for flight in the current environment of a penguin. |
| embryology | The study of multicellular organisms as they develop from fertilized eggs to fully formed organisms. |
