Here's the ninth question my students have to answer. This is the end of the series since the test is tomorrow.
The positions of animals, fungi, and plants in the eukaryotic tree of life have been clear for decades. So why is there so much controversy today about how to construct a valid tree of eukaryotes? What are the main problems, according to Keeling et al. (2005), and how will those problems be overcome?
