Classification and reclassification: genetic evidence
I can describe the classification, and sometimes reclassification, of organisms based on evidence from their gene sequences.
Classification and reclassification: genetic evidence
I can describe the classification, and sometimes reclassification, of organisms based on evidence from their gene sequences.
Lesson details
Key learning points
- Organisms can now be classified using evidence from sequencing their genes
- Comparing gene sequences provides evidence of evolutionary relationships
- Sometimes organisms are reclassified into a different group if new evidence is discovered
Keywords
DNA - Deoxyribonucleic acid is a chemical that carries genetic information, and it is the molecule of inheritance.
Gene sequence - the sequence of DNA that codes for a particular protein
Evolutionary trees - diagrams that show the evolutionary relationships between organisms
Common misconception
Organisms evolve over a short period of time.
Draw pupils attention to the tome scales on the evolutionary trees to show that evolution takes place slowly over long periods of time.
