A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The course begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

Course learning outcomes

After studying this course, you should be able to:

  • Understand the patterns and processes of evolution above the species level
  • Appreciate the differences between the three methods of phylogenetic analysis: evolutionary systematics, phenetics, cladistics.
