Summary
This week, I learned about cladograms, and how scientists use them to organize data about common traits among animals. Cladograms are designed in a linear fashion to represent the growing complexity of trait, and the possible connections between animals. Cladograms allows scientists to examine possible common ancestors between animals and the traits that those common ancestors shared. Cladograms allow you to organize traits and allow you to find the most common traits among species. This can be especially useful because animals are complex in their traits, and as species evolve, it can be very difficult to find commonality between them.
S&EP - Using Models
This week, I was able to use models, such as cladograms, to find similarities between animals and how they connect to each other through common ancestors. on e example of this is the trying to find the most common ancestor of the T-Rex. The first thing that I had to do was make the cladogram and put the most basic trait in the beginning, in this case being vertebrae. I used a chart to help organize which animals had the most common traits to the T-Rex. Then, I was able to narrow it down further into 2 main species that could possibly be the closest common relatives. Those species were the Caiman and Parrot. I was then able to get more specific with traits that might be common with the T-Rex. In the end, the Parrot had the most common traits with the T-Rex, making it the most common ancestor.
XCC - Patterns
Patterns can be very visible in cladograms. I say this because cladograms all present a sense of connection between species, and all follow the pattern of having the most specific shared traits at the top of the line, and the most basic traits at the bottom. This pattern can help scientists further examine specific traits that are present in a species, and how it compares to others. The pattern is universal, in the sense that all cladograms follow it and definitely help figure out common ancestors between species.
