Today was day one of two investigating other methods of relatedness among organisms. So far we have focused on how organisms that are similar to each other tend to look similar. However, there are many other ways to compare relatedness including homologous, analogous, and vestigial structures as well as the type of cell that makes up an organism. Tomorrow we will share out what we've learned with our partner groups and continue our discussion of relatedness among all organisms.
