Cladograms, cladograms, cladograms 10/22/17

Summary:
When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time.
S&EP-Models:
Cladograms are a diagram or model that show how closely related certain organisms are and what traits they share. I constructed one of my own cladograms to represent and understand the differences between certain dinosaurs. In order to build this model, I identified the different traits of the organisms and labeled which had them and which didn't. After that, I made a Venn diagram with having the most common trait on the outside. I then used all this information to create a cladogram to represent all the traits shown on the dinosaurs. I used models to explain the differences and how closely related some dinosaurs were. If we apply this to the image above, you can see that the ring-tailed lemur and the spider monkey are more closely related than the ring-tailed lemur and the chimpanzee. This is because they have a closer common ancestor, represented by where the lines meet, and they share more characteristics. Although building models of cladograms deepened my understanding of them, I still wonder why the space between each animal didn't vary considering they didn't all evolve at a continuous rate?
XCC-Patterns:
In every cladogram, you can see a pattern. The organism with the most traits in on the top and the least is on the bottom, the diagonal line of a cladogram represents time and the points in which two lines meet are where the two living things share a common ancestor. This pattern can be applied to almost everything. To begin studying cladograms we used this pattern when working with the traits of dinosaurs, as well as when we identified the traits with the sports balls. Knowing that cladograms follow a pattern we can easily identify which animals, plants, or balls are more closely related. Like with the sports balls I would say that the volleyball and basketball are more closely related than the basketball and golf ball because not only are they closer, but they share more traits. These traits include, being inflatable, used indoors and a meant to bounce. This pattern can clearly apply to multiple living things and can definitely help me see evolutionary relationships between living things.
Multiplier: This week I was a mutant, to be more specific a learner because I wanted to catch up on what I missed on Wednesday.
