Evolution - Comparative Structures Lab
The artifact that I have chosen to discuss for the unit of evolution is this picture of a sheet we had to analyze during our comparative anatomy lab. In this lab, we were given a variety of different animals and their physical features. For each set of diagrams, we had to analyze various details that we observed and compare/contrast them to the same structure in a human. From this, we could gather how far along the evolutionary line humans were when compared to other animals, and which apes were the oldest among the given group. This artefact in particular connected to the unit of evolution because it gave us the arm structures of various animals who live in very different environments. We had to compare the bone structures and give reasons as to why a specific bone helped the animal to live in its environment. This activity was significant to me because I was able to develop my analytical skills because in this activity, we had to write down and record even the smallest observations we noticed, therefore a keen eye and open mind was required. I don’t think I can directly apply this knowledge in real life because in my life, there aren’t very many opportunities for me to display my knowledge of evolution (other than future biology courses in grade 12 and university). However, as I’ve discussed with previous artefacts, the character-building skills I’ve learned from this activity will help me in real life because I plan to be a psychiatrist, and when my patient is discussing their life with me, I have to be able to sort out the important information and write down the smallest observations I make. This activity helped me to understand the course better because I learned more about us as humans, and how precious our mind is. I also got a chance to see and assess the way evolution works. For example, by comparing the hands/feet of various primates and creating a cladogram, I was able to decide for myself which traits evolved before others and I had to think about the environments and the factors which led to the development of those traits. I find it amazing that just a few evolutionary changes have separated us from other animals to such a large degree. In conclusion, I believe that this activity was very good for us to do as biology students and we can apply the skills used in this activity (analyzing, perception) in various situations we encounter in real life.
