- Compare the phylogenetic tree of protists with the secondary endosymbiosis theory which proposes how photosynthetic protists evolved. Are both reconcilable? Explain.arrow_forwardAs we have discussed in class, phylogenies are hypotheses, and can therefore change over time with new evidence. Relatively recent and strong molecular evidence (that we did not discuss in class) suggests that all members of the Subphylum Hexapoda are derived from a common ancestor within the Subphylum Crustacea, as in the cladogram shown below. Given this new information, answer the question below. Note: Don't panic. Some of the names of these groups are new to you (Copepoda, Malacostraca, and Remipedia are all classes or subclasses within the Subphylum Crustacea), but this will not affect your ability to answer this question. Myriapoda Copepoda (Crustacea) Malacostraca (Crustacea) Hexapoda Remipedia (Crustacea) If we insisted that all groups must be categorized and named so that taxonomic ranks/names always include a single common ancestor and all of its descendants, how would this new evidence change our definition of a hexapod? Hexapoda and Melacostraca would have to be classified…arrow_forwardMake alist of features and processes that you think might have been passed down from leca to modern eukaryotesarrow_forward
