1. Zoology 250, Tree of Life test Test your knowledge of the locations of phyla on the “Tree of Life” For each clade or branch tip, the first image will indicate the clade or branch in red with a question mark (?), and a question asking about the name of that clade/branch. Once you think you know the name of the clade/phylum, go to the next image to see if you are correct. The cladogram of animal relationships in this quiz is the one followed in Zool 250; don’t forget that different authorities have different opinions and that clades can always be rotated around their basal node.
