IGNOU MZO-04 (January 2025 – December 2025) Assignment Questions
1. Discuss the evidence supporting the RNA World Hypothesis and its implications for understanding the transition from prebiotic chemistry to cellular life.
2. Discuss the role of horizontal gene transfer in shaping the evolutionary relationships among domains of life.
3. What is the concept of speciation in bacteria, and how does it differ from speciation in eukaryotic organisms?
4. What is the molecular clock? Describe how is it used to estimate the timing of evolutionary events?
