Found on the Smithsonian blog today about the differences in brain size and whether the animal has a smooth brain or a wrinkled brain. Which are similar and which are different? In the article Nuwer makes observations of how three of the animals have brains that are shaped as a liver. Very interesting. Why does she say this? What shape is a liver?
Great image from the blog mentioned above to learn about shapes, patterns and even math. I say math because they did give us a scale at the bottom of the image that students can measure each brain to get an idea about the size and area. Tracing, they could place a thin sheet of paper over each brain and trace the brains. Make a lapbook and take this even more in depth and study each animal. Lots that can be made just by this one article. I am not an evolutionary thinker so I can read this without wondering why the brains are so similar because I know I did not start as a monkey or evolved from the grey squirrel.
