Chickens have a similar bone structure, on a smaller scale, to Tyrannosaurus rex. Moreover, genetic analysis of proteins from modern chickens has revealed surprising similarities between the DNA of the two species. It follows that chickens are descended from T. rex. This is also evidenced by the fact that scientists believe dinosaurs were the first animals to evolve feathers. Which statement best represents the conclusion of the argument?
a. Evidence suggests that dinosaurs were the first animals to evolve feathers.
b. Chickens have a similar bone structure, on a smaller scale, to T. rex.
c. Genetic analysis of proteins from modern chickens has revealed surprising similarities between the DNA of the two species
