Across
- 2. A place where unique species often evolve (hint: think of biogeography).
- 4. When individuals move to a new population and bring genes.
- 6. To change over generations so organisms fit their environment better.
- 10. Remains of plants or animals from long ago.
- 11. Proof used to support ideas in science (fossils, DNA, observations).
- 12. Random changes that can make genes more or less common by chance.
Down
- 1. A group of the same species living in one area.
- 3. The molecule that stores genetic information in all living things.
- 4. A change in DNA that can create a new trait.
- 5. To watch something happen directly (like tiny organisms evolving).
- 6. A version of a gene (like blue vs brown eye color).
- 7. A strong scientific explanation tested many times.
- 8. A characteristic an organism can have (color, size, etc.).
- 9. When helpful traits become more common because individuals survive better.
