Across
- 3. A group of organisms of the same species, living in one specific area at one time
- 5. Occurs when phenotypes in the middle of the range are selected against
- 6. Occurs when phenotypes at both extremes of the phenotypic distribution are selected against
- 7. Traits than an entire population has because they help them better fit in their environment
- 9. Occurs when one of two extreme phenotypes is selected for
- 11. When populations grow exponentially, with the species producing more individuals than an environment's resources can support
- 12. This is caused by random mutations that create differences in organisms
- 16. Type of adaptation that is an action the organism chooses to do
- 17. When an individual gets used to their environment and changes their behavior to get more comfortable
- 18. The emergence of new species (usually one splitting into two)
Down
- 1. The changing of organisms over time
- 2. Type of adaptation that is a certain feature or shape of the body
- 4. Organisms with traits that allow them to survive and reproduce pass on their genes
- 8. An organism’s ability to survive and reproduce
- 10. Occurs when organisms must fight to survive because resources or mates become scarce
- 13. Type of adaptation where a special function is enacted by part of the body
- 14. External agents which affect an organism’s ability to survive in a given environment
- 15. Traveled to the Galapagos Islands and founded the theory of evolution
