Across
- 3. The total collection of genes and genetic variations present in a population.
- 4. A change in the genetic material (DNA) of an organism, which can lead to new traits and contribute to evolutionary change.
- 5. A characteristic or behavior that helps an organism survive and reproduce in its environment.
- 7. When two related species become more dissimilar over time, often due to different environmental pressures.
- 8. The process where unrelated species develop similar traits or adaptations due to similar environmental pressures.
- 9. The process by which one species splits into two or more distinct species due to genetic differences and environmental factors.
- 12. The process by which humans intentionally breed plants or animals for specific traits, often seen in agriculture and pet breeding
- 13. The collection of fossils used to track the history of life on Earth and understand evolutionary processes.
- 14. The most recent species from which two or more different species have evolved.
Down
- 1. The process by which different species of organisms develop and change over generations through variations in traits and natural selection.
- 2. Body parts in different species that have a similar structure and origin, suggesting common ancestry.
- 6. Environmental factors (e.g., climate, food, predators) that influence which traits are favorable for survival.
- 10. The process where organisms with traits that better suit their environment are more likely to survive and reproduce, passing on those traits.
- 11. The differences in traits among individuals within a population, which can be genetic, behavioral, or physiological.
