Compare the phylogenetic tree of protists with the secondary endosymbiosis theory which proposes how photosynthetic protists evolved. Are both reconcilable? Explain.
Which group of protists are scientists most likely to find as fossils? Which groups are least likely to be fossilized? Explain your reasoning.
Please briefly describe the idea of endosymbiosis and its role in protist evolution-relate to the idea of function of the group.
