Here are several key concepts related to the theory of evolution expressed as subject-predicate-object triples:

1. **Theory of Evolution** - describes - the process of natural selection.
2. **Natural selection** - is a mechanism of - evolution.
3. **Species** - evolve through - genetic variation.
4. **Genetic variation** - is caused by - mutations.
5. **Mutations** - can lead to - new traits.
6. **Organisms** - compete for - resources.
7. **Favorable traits** - increase - survival and reproduction.
8. **Unfavorable traits** - decrease - survival and reproduction.
9. **Population** - changes over time due to - evolutionary pressures.
10. **Fossil records** - provide evidence for - evolution.
11. **Common ancestry** - explains - the similarities among species.
12. **Adaptive radiation** - occurs when - species evolve into many forms.
13. **Speciation** - is the process of - forming new species.
14. **Geological time scale** - measures - the age of Earth.
15. **Homologous structures** - indicate - shared ancestry.
16. **Analogous structures** - demonstrate - convergent evolution.
17. **Biogeography** - studies - the distribution of species.
18. **Artificial selection** - is a human-driven form of - selection.
19. **Evolutionary theory** - is supported by - multiple scientific disciplines.
20. **Evolution** - explains - the diversity of life on Earth.
