Across
- 3. of different genes in a population
- 5. identificatin of species
- 8. unrelated species with similar features
- 10. cratures with no apparent strucures
- 13. large changes in a species
- 16. prevents different species from reproducing
- 17. species become unified overtime
- 19. species change to its environment
- 20. change in dna that effects the protein productions
- 21. reduction in population
- 22. small changes in a species
- 23. species changing
Down
- 1. modification of an organism
- 2. only the species that adapt survive
- 3. random changes in gene pools
- 4. related species that dont share similar features
- 6. species slightly shift overtime
- 7. physical seperation of members in a population
- 9. comparing different species
- 11. progressive series o fossels
- 12. exteme gene or phyisical change overtime
