Across
- 2. Provides new alleles that introduce new variations
- 5. Organisms inherit different versions of traits
- 7. Ship Darwin sailed on to the Galapagos
- 10. Over time, the population of organisms changes to be best suited to the environment
- 12. Surviving organisms pass on their genes more frequently
- 13. A few members of a population start a new population
- 16. More offspring are born than can survive
- 18. Evolution shows that each species is adapted to its environment
- 19. Selects for one extreme
- 20. Small scale evolution that causes change within a species
- 21. Came up with the incorrect Theory of Inheritance of Acquired Traits
- 22. Change in allele frequency due to random chance
- 23. Movement of alleles in or out of a population when organisms migrate
Down
- 1. Organisms with the best variations for an environment live
- 3. Organisms must compete for the resources that are available in the environment
- 4. Selects for both extremes and eliminates average
- 6. Gradual accumulation of adaptations in a population over time
- 8. Process in which organisms with favorable adaptations survive, reproduce, and pass on their variations to the next generation
- 9. Came up with the Theory of Natural Selection
- 11. Individuals choose mates according to their physical traits
- 14. Eliminates genes from a population (ex: natural disasters)
- 15. Selects for average individuals
- 17. Evolution shows that all organisms have the same characteristics of life
- 22. All the alleles of a population’s genes
