You should include 1-2 sentences on the methods and then the overall reason. In my opinion, this week lab covers our inner animal and how we compare with other animals per different part of our body. We were able to see the differences and similarities to certain animals. We noticed for example, how the evolution from apes and monkeys, one with tail and one without it, to us by looking at the back in lab. Comment: This lab exercise explores how species are related. We can see this by comparing anatomical structures and how they change over time. Part 7 of 7 - Lab Upload 8.0 Points Question 31 of 318.0 Points Please upload your completed Lab Packet for this week. Make sure your name is on the top in the space provided. Comment: This past week explored how species descended from a common ancestry based on similarities in structures and functions. [Show More]
