Across
- 2. The study of the distribution of organisms across the Earth and how it relates to their evolutionary history.
- 3. An environmental factor that influences which individuals survive and reproduce, driving evolution (e.g., predators, disease, or competition).
- 6. The intentional breeding of organisms by humans to enhance desirable traits (e.g., breeding plants or animals for specific characteristics).
- 10. The formation of new species when populations of the same species become reproductively isolated and evolve differently over time.
- 11. Hybridisation
- 12. A specific characteristic or feature of an organism, such as eye colour, height, or leaf shape.
- 13. Unrelated species evolve similar traits due to similar environments or functions (e.g., wings of bats and birds).
- 14. Preserved remains or impressions of organisms from the past, found in rocks or other materials, that provide evidence of evolution.
- 15. Random changes in the frequency of alleles in a population, often having a greater effect in small populations.
- 16. The study of the development of embryos, which can show similarities between different species, indicating common ancestry.
Down
- 1. Structures with the same origin but different functions (e.g., human arms and whale fins).
- 4. The process where organisms better adapted to their environment survive and reproduce, passing on beneficial traits.
- 5. Related species develop different traits due to adaptation to different environments (e.g., Darwin’s finches).
- 6. Structures with different origins but similar functions (e.g., wings of birds and insects).
- 7. The ability of an organism to survive or tolerate harmful factors, such as antibiotics, pesticides, or environmental stress.
- 8. Differences in traits or characteristics among individuals in a population, caused by genetic or environmental factors.
- 9. The total collection of genes and their variations within a population at a given time.
