Across
- 3. a mechanism of evolution based on adaptions, fitness, and heritable traits
- 4. similar DNA and amino acid sequences
- 5. similar anatomy from common ancestors (eg. forelimbs of human/cat/whale/bat)
- 9. structures w/ little or no use (eg. flightless bird wings, appendix, whale thighs)
- 10. the founding of a small population can lead to genetic drift
Down
- 1. similar early development
- 2. similar structures, function in similar environments
- 6. characteristics in related species can have underlying similarity even though functions may differ
- 7. the movement of alleles between populations
- 8. a change in allele frequencies due to chance
