Evolution 1-4
Across
- 1. elimination of a species
- 4. 2 organisms change in order to form a specialized relationship
- 5. radiation/divergent evolution a number of different species from one common ancestor
- 6. equlibrium bursts of change followed by periods of stability
- 9. structures similar function, different structure
- 10. population shows different species on different islands
- 13. comparing similarities in DNA and AA sequences in different species to find common ancestry
- 16. tree diagram that predict the evolutionary relationship between organisms
- 19. structures structures with little or no function to the organism
- 20. remnants of animals
- 21. pool
- 24. random change in frequency of alleles in a population
- 25. reproduction process of binary fission or mitosis where only one parent produces offspring
- 26. reproduction takes 2 organisms to produce offspring
- 27. fossils fossils that link extinct species to current species
- 28. evolution unrelated species evolve similar characteristics
- 29. large scale
- 30. traits that arent good but necessary to reproduce
- 31. small scale
Down
- 2. Survival of the fittest
- 3. structures similar characteristics resulting from common ancestry
- 7. classifying and assigining each organism a name
- 8. the study of fossils
- 11. the structure of an organism
- 12. the embryos of vertebrates are very similar in appearance
- 14. movement of genes in or out of a population
- 15. forming of a new species by evolution from pre-existing species
- 17. slow changes over a long period of time
- 18. evolution,
- 22. no changes in the allele frequency of a population
- 23. evolutionary history of a species or group of a related species
