Evolution. Thats our first unit in Biology. I was amazed over the fact how we are related so many animals when we looked at “Comparative DNA”. Anyway, over the past 2 lessons, we have been learning about how to draw a proper Venn diagram and cladogram. The cladogram is like a family tree but saying who we are more related to through a common ancestor. For the Venn Diagram, I only used it in math and it was circular. What we did in class was more of a square. I didn’t know that you could put 2 bubbles inside a bigger one. That was pretty interesting. Below is a picture of a bubble inside another bubble. It means that they all have “Mesoderm” but however some grow the “Head” first rather than the “Anus”, hence there being 2 separate bubbles in a bigger bubble.
