- 3. remains of a ancient organisms
- 5. ex: similarities in the bones of whale and human hip bones
- 6. more than 1 of the same species
- 8. perfect society, no evolution happens here
- 11. evolution on the species level
- 12. selection which favors intermediate traits
- 13. all the alleles in a population
- 14. selection that favors 1 extreme
- 15. a union of ideas from several biological specialties which provides a widely accepted account of evolution
- 18. when natural disasters reduce a population and reset the gene pool
Down
- 2. the study of allele frequency and distribution
- 4. when a natural disaster wipes of the population, resetting the gene pool
- 7. movement of traits between 2 populations
- 9. adjustment in individual that allows it to better survive
- 10. mechanism of evolution, known as survival of the fittest
- 16. formula formula used to calculate the allele frequencies in a perfect society
- 17. mechanism of evolution, chance that an allele disappears from the gene pool
- 19. the gradual change in species that leads to better suited species
- 20. total number of fossils discovered and the information that has been derived from them
