Molecular evolution examines DNA and proteins, addressing two types of questions: a. How do DNA and protein molecules evolve? b. How are genes and organisms evolutionarily related? 2. Population genetics focuses on changes between generations. Molecular evolution considers the hundreds or thousands of generations needed for speciation, where small departures from Hardy-Weinberg equilibrium, random effects and slight differences in fitness can become very significant. 3. Development of techniques in molecular biology makes it possible to study molecular evolution, using genomes as historical records that can: a. Reveal the dynamics of evolutionary processes. b. Indicate the chronology of change. c. Identify phylogenetic relationships between organisms.application/ppt1288192 bytesapplication/vnd.ms-powerpointzh-TWlearning objecthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2006092815540077/1/ch24.ppt
