INSTRUCTIONS:
1. On the branches of the phylogenetic tree on the back side of this worksheet, write in a unique derived trait (Autapomorphy), either anatomical
or behavioral, that is used to distinguish each primate subgroup from the other taxa of primates. The points where the derived traits should
be entered are labelled A1 - A6 and a written description of what is expected for each appears below and to the right of the tree.
2. On the trunk of the phylogenetic tree write in a shared derived trait (Synapomorphy) that unifies the branches (clades) of the tree which sit
to the right of the trait marker (S1-S5). Again these traits can be either anatomical or behavioral and a written description of what is
expected for each appears below and to the right of the tree.
For both #1 and #2 you should write in at least one trait for each trait marker (A1-A6 and S1-S5) that appears on the phylogenetic tree. Make sure
all entries are detailed enough to differentiate taxa and written legibly. If I can't read it, I can't give you credit for it.
Definitions:
Taxon (singular; taxa-plural): A unit in the biological system of classification of organisms, for example: a phylum, order, family, genus, or species.
Unique Derived Trait (Autapomorphy): a distinctive anatomical or behavioral trait that is unique to a given taxon and is useful in distinguishing the taxon from
other similar taxa.
Shared Derived Trait (Synapomorphy): an anatomical or behavioral trait inherited by multiple taxa from a common ancestor and, thus, indicative of an evolutionary
relationship between the taxa.
