Evidence for Evolution
1. Fossil Record:
- Fossils show a gradual progression of species over time.
- Transitional fossils, such as Archaeopteryx, bridge the gap between different groups of organisms.
- The fossil record supports the concept of common ancestry.
2. Comparative Anatomy:
- Homologous structures, such as limbs in vertebrates, show similarities in structure despite different functions.
- Vestigial structures, such as wisdom teeth in humans, are remnants of ancestral structures no longer essential.
- Analogous structures, such as wings in bats and birds, serve similar functions but have different origins.
3. Molecular Biology:
- DNA and protein sequences show similarities between different species.
- The more closely related two species are, the more similar their genetic material will be.
- Phylogenetic trees based on genetic data show the evolutionary relationships between organisms.
4. Geographic Distribution:
- Species often have specific geographic distributions due to their adaptations to specific environments.
- Closely related species may live in adjacent areas, while more distantly related species may live in more disparate locations.
- This suggests that species have evolved and diversified over time in response to geographic isolation and environmental pressures.
5. Natural Selection:
- Natural selection is the process by which individuals with beneficial traits are more likely to survive and reproduce in a particular environment.
- Over time, this process can lead to the accumulation of beneficial traits and the evolution of new species.
- Natural selection can be observed in nature, such as the evolution of antibiotic resistance in bacteria.
