1. Draw a phylogenetic tree for animals including at least one species from each of the following groups in your ecosystem:
● 4 different invertebrate species from 3 different taxonomic groups.
o Remember: invertebrates are found within the sponges, diploblasts, and protostomes.
● 6 different deuterostome species from 6 different taxonomic groups.
o Remember: deuterostomes are found within the echinoderms, hemichordates,
chordates.
a. In the space below this prompt, write the common & scientific names of the 10 animal species that you
selected to include in your phylogeny. (1 point)
b. Draw the phylogeny of the 10 animals from the different taxonomic groups, and make sure to label the
branches with the associated species names. Only draw branches for these 10 species. The branches
should reflect the correct evolutionary relationships among the species. (3 points)
c. Label the common ancestor for each clade on the phylogeny. You can use general terms for the
ancestors. For instance, if you were labeling a phylogeny that included plants and animals, the
common ancestor would be “eukaryote.” (2 points)
d. Label the nodes with the major differences between the lineages. (2 points)
