Evidence for Evolution
- Fossils: Show how organisms have changed over time
- Antibiotic resistance: Bacteria evolve resistance — we can see it happen!
- DNA: Similar genes in related species
- Homologous structures: Same bone structure in different animals (e.g., arm, wing, flipper)

Quick recall flashcards
What is evolution?
The gradual change in the inherited characteristics of a population over many generations through the process of natural selection. It can lead to new species forming over very long time periods.
