Natural Selection
Across
- 1. the dynamic evolutionary process that fits organisms to their environment
- 4. selection only allows the selected traits to be passed through successive generations
- 5. an interaction between organisms or species in which both are harmed
- 10. type of reproduction that involves two individuals
- 11. the passing of traits
- 12. the act or fact of living or continuing longer than another person or thing
- 13. drift the change in the frequency of an existing gene variant in a population
- 14. Darwin best known for his contributions to the science of evolution
- 15. product of reproduction, produced by one or more parents.
- 17. provides living things with everything that is necessary to survive
- 18. how a new kind of plant or animal species is created
- 20. difference in characteristics among the individuals of the same species
Down
- 2. a specific characteristic of an organism
- 3. change in the heritable characteristics of biological populations over generations
- 6. means that each generation has more offspring than can be supported by the environment
- 7. selection process whereby organisms better adapted to their environment tend to survive and produce more
- 8. a random change to genetic material
- 9. biological process by which new individual organisms are produced
- 16. occurs when species are diminished because of environmental forces
- 19. type of reproduction that does not involve the fusion of gametes
