What does genetic variation within a population signify for species adaptation?
What does genetic variation within a population signify for species adaptation?
Genetic variation provides the raw material for natural selection, allowing species to adapt to environmental changes.
How have advances in molecular phylogenetics impacted classification systems?
How have advances in molecular phylogenetics impacted classification systems?
Molecular phylogenetics, through DNA sequencing, allows for more accurate classifications based on genetic relationships rather than just morphology.
Explain the role of natural selection in evolution.

Study Notes
B5.2a Genetic Variation
- Genetic variation is common within species populations.
B5.2b Impact of Developments on Classification
- Developments in biology have influenced classification systems.
B5.2c Evolution through Natural Selection
- Evolution occurs through natural selection.
- Variations arise, and those better suited to the environment thrive.
- Favourable traits are passed to subsequent generations.
B5.2d Evolution as a Change in Characteristics
- Evolution is a change in inherited traits within a population.
- This change occurs over time due to natural selection.
- New species can result from this evolutionary process.
B5.2e Evidence for Evolution
- Evidence for evolution is diverse.
- Fossils and antibiotic resistance in bacteria are examples.
B5.2f Darwin and Wallace and the Modern Impact
- Darwin and Wallace developed the theory of evolution by natural selection.
- This theory significantly impacted modern biology.
- Seed banks are a tool for preserving biodiversity.
