EVOLUTION
This Class 12 Biology page gives the two key diagrams of Chapter 7 Evolution: Miller's experiment on the origin of life, and the three types of natural selection (stabilising, directional and disruptive) shown with the Hardy-Weinberg principle, each described with all labels.
CHAPTER 7 - EVOLUTION
1. MILLER'S EXPERIMENT
[Figure: Apparatus of Miller's experiment. A large spherical flask at the top holds the gases CH4, NH3, H2O and H2, with Electrodes at the top producing a Spark discharge. A tube on the left leads To vacuum pump. A Condenser on the right has Water in and Water out, with Water droplets falling below it. A flask of Boiling water at the lower left sends vapour up and round the circuit. At the bottom is a trap holding Liquid water in trap, and Water containing organic compounds collects from the condenser. Arrows show the direction of circulation]
2. HARDY - WEINBERG PRINCIPLE, TO SHOW OPERATION OF NATURAL SELECTION
[Figure: A normal bell-shaped curve on the left with the axis labelled Number of individuals with phenotype, marked Phenotypes favoured by natural selection and Medium-sized individuals are favoured. Three arrows lead from it to three graphs: (a) STABLISHING (Stabilising Selection): Peak gets higher and narrower. (b) DIRECTIONAL (Directional selection): Peak shifts in one direction. (c) DISRUPTIVE (Disruptive Selection): Two peaks form]
