Surgical (sterilisation) – permanent prevention
💡 Final Advice & Masterclasses!
🔥 These topics are predicted, but anything from the syllabus could appear—so revise widely!

✅ Classification – grouping organisms based on similarities
✅ Fossils – evidence for evolution, show how species have changed over time
✅ Evolution – species gradually change to adapt to their environment
🧬 Theory of Evolution
✅ Charles Darwin’s theory – natural selection (survival of the fittest)
✅ Mutations cause variation, and beneficial traits get passed on
✅ Over time, this leads to new species forming
🧪 Cloning
✅ Types of cloning:
Cuttings & tissue culture (for plants)
