A major evolutionary challenge, for both plants and animals, was the colonization of land. Thinking about these challenges for both groups, please answer the questions below:
A. What are two similar challenges faced by both plants and animals? For each challenge please give an adaptation found in each group, plants and animals, evolved to deal with these challenges. (4 points)
B. We think plants colonized land in one evolutionary event, but we also think this happened multiple times in animals. What major animal phyla did we discuss were able to successfully colonize land? (3 points)
C. For two of the phyla you used to answer part B, give a pre-adaptation that assisted this group in colonizing land and mention how it was useful. Can you think of a pre-adpatation in plants that helped them colonize land? (3 points)
