Animal Dissections
For a little more than two weeks, we dissected a series of animal phyla and observed the external and internal anatomy. We later compared them to each other and saw how the animals slowly evolved from simple structures to more complex structures and functions.
here are the links to my dissection write-ups:

Below is a chart of a comparison of major animal phyla; we compared the animals we dissected through different characteristics, and saw how they evolved different functions.
