Ch-10: Evolution
This chapter introduces the Theory of Evolution by Natural Selection, explaining how living organisms gradually change over generations through the process of adaptation and survival. Students will learn how Charles Darwin developed his theory after observing the diversity of life during his famous voyage on HMS Beagle, particularly his studies of the Galápagos Islands.
The notes describe the key observations made by Darwin and explain how these discoveries led to the concept of natural selection, where organisms with favorable characteristics are more likely to survive, reproduce, and pass their traits to future generations.
Students will also study the major evidence
Ch-09: Plant Reproduction
