Evolution
Across
- 3. Differences in physical traits of an individual from the group to which it belongs
- 5. Group of organisms that are closely related and can mate to produce fertile offspring
- 8. Ability of a trait to be passed from one generation to the next
- 9. Process of becoming adapted to an environment, change that improves a population's ability to survive
- 10. Body part that are similar in structure on different organisms but performs different functions
- 12. Measure of an organism's ability to survive and produce offspring relative to other members of a population
- 13. Group of organisms of the same species that live in a specific geographical area
- 15. Body part that is similar in function as a body part of another organism but is structurally different
- 16. Trace or remains of an organism that lived long ago
Down
- 1. Model of evolution in which gradual change over a long period of time leads to biological diversity
- 2. Study of the geographical distribution of living organisms and fossils on Earth
- 4. Remnants of an organ or structure that functioned in an earlier ancestor
- 6. Process of change by which new species develop from preexisting species over time
- 7. Theory that state that natural disasters shaped Earth's landforms and caused extinction of some species
- 11. theory that states that the geological processes that shape Earth are uniform through time
- 14. Study of fossils or extinct organisms
