Classification — FAQ
Frequently asked questions for 9700 Classification. Direct answers first, then deeper explanation — then practise with marking.
Why is classification important in Biology 9700?
Classification is crucial for Cambridge 9700 Biology students as it provides a universal system to identify, name, and group organisms. It helps us understand the diversity of life, trace evolutionary relationships, predict characteristics of newly discovered species, and manage biodiversity. Master it with our free course and practice past papers.
What's the difference between traditional and modern classification methods?
Traditional classification primarily relied on observable physical characteristics (morphology and anatomy). Modern classification, however, heavily incorporates molecular evidence like DNA base sequences and protein amino acid sequences, providing a more accurate and objective reflection of evolutionary relationships or phylogeny.
Can two different species produce offspring in Cambridge Biology 9700?
According to the biological species concept, two different species cannot produce fertile offspring in nature. While some closely related species might interbreed (e.g., a horse and a donkey producing a mule), their offspring are typically sterile, preventing gene flow between the parent species. This is a key limitation of the concept.
