Evolutionary Relationships in Mammals
For this scientific argument, the research question was Which of these mammals are the most closely related? At first, my claim had stated “The mammals with more similar traights and characteristics were the ones that were the most closely related.” As my group and I looked deeper into the data, we had analyzed the different mammals and ended up with a final claim which was “The elk, cow, Caribou, the Pallid bat, and big eared bat are the most closely related.” Our evidence to support this claim is all in the data table 6.1 and 6.2, which is the amino acid sequence for hemoglobin subunit alpha protein. In the first four amino acid sequences we had noticed the Elk, Cow, Pallid Bat, and Mouse not only shared the amino acids M , V, and L , but they all had started off with the M amino acid in the very first sequence. In sequence 5 it switches up and shows how the Tulk, Carribou, Cow ,Big-Eared Bat, Golden Hamster, and Nine-Banded Armadillo share similar A amino acids while the mouse has a G amino acid and the pollid bat has a P amino acid. In sequence 6 , we can really see things start to branch off. The Caribou, Cow, Palid Bat, Big Eared Bat, ad Nine Banded Armadillo all share similar amino acid were as the Musk Shrew, Mouse, and Golden Hamster actually mutated from one another. Sequences 7 and 8 , all mammals have the same amino acids and once again it changes in sequence 9 but goes back to being the same in sequence 10 except the Nine-Banded Armilldilo who has an H amino acid. The Mouse and the Golden Hamster are the only 2 mammals with the same amino acid in sequence 11 and in sequences 12 and 13, the Golden Hamster is the only mammal with the S & E amino acid. Amino acid sequences 14 through 20 goes back and fourth , meaning, sequence 14 is all the same except the Nine-Banded Armadillo , sequence 15 is all the same W amino acid, sequence 16 the Pallid Bat, Big-Eared Bat, and Musk Shrew
