1) List the traits in the order in which they appear from an evolutionary standpoint. You will start with multicellularity, then tissues, then radial symmetry and so on and so forth. (20 points)2) Define all traits. (20 points)3) Determine the organism the trait was first found in. Be sure to list only the organism the trait was FIRST found in. Hint! You can determine this by using the phylogenetic trees in your textbook. Starting on page 699 there is a phylogenetic tree with some of the traits. More mini-phylogenetic trees can be found on subsequent pages (702, 704, 705, etc and ending on page 880) (20 points)4) Provide the evolutionary advantage of each trait. (20 points)

Part A – (possible 80 points)
For Part A there are 4 parts you need to include – see numbered bullets below. You are to make a
chart detailing the acquisition of traits from sponges to mammals. It may be done in the form of a
table, a concept map, an outline, or a phylogenetic tree. The following traits must be included and
defined, along with the evolutionary advantage(s) of each and the organism that first exhibited the
trait.
1) List the traits in the order in which they appear from an evolutionary standpoint. You will
start with multicellularity, then tissues, then radial symmetry and so on and so forth. (20
points)
2) Define all traits. (20 points)
3) Determine the organism the trait was first found in. Be sure to list only the organism the
trait was FIRST found in. Hint! You can determine this by using the phylogenetic trees in
your textbook. Starting on page 699 there is a phylogenetic tree with some of the traits.
More mini-phylogenetic trees can be found on subsequent pages (702, 704, 705, etc and
ending on page 880) (20 points)
4) Provide the evolutionary advantage of each trait. (20 points)
