Evolution
Why do fossils, embryos and DNA tell the same story of change. This chapter in NCERT Class 12 Biology, Chapter 6, traces ideas from Lamarck and Darwin to modern synthesis, with evidence from fossils, anatomy, embryos and molecules. It explains mutation, selection, drift, Hardy-Weinberg equilibrium, speciation and human origins. You will learn how antibiotic resistance demonstrates evolution in action and why variation, inheritance and time together produce the diversity of life.
