S6: Classical descriptive and clueless biology found a theoretical framework in the evolutionary theory of Darwin P: In later years, the focus was physiology and internal morphology or anatomy. Q: Darwinian ideas of evolution by natural selection changed the perception completely. R: The growth of biology as a natural science during the last 1000 years is interesting from many points of view. S: One feature of this growth is changing emphasis from mere description of life forms to identification and classification of all recorded living forms. The correct sequence should be
