unique four-chambered stomachspecialized to digest tough,fiber-filled grasses.Researchers studying ruminants are investigating themorphological and molecular characteristics of different ruminant families in order to determine theevolutionary relationships among the families.Cladograms of several ruminant families were constructedbased on morphological data(Figure 1A)and molecular data (Figure 1B).Table 1 shows a sample of themorphological characteristics present in each family used to construct the cladogram in Figure 1A.  \nA  \nB  \nFigure 1.Cladogram of six ruminant families based

comparison of the DNA sequences of different1 pointorganisms to suggest the most likely evolutionary relationship among the organisms.  \n·  The(DNA)sequences of organisms that are more closely related are more similar     (than those of organisms that are less closely related).                   \n(b)Based on Figure 1,explain why Bovidae is likely to be more closely related to Moschidae1

molecular data/Figure 1B support(s)this relationship.)Morphological similarities    may not reliably indicate evolutionary relatedness.                  \n(c)Using the template in the space provided for your response,represent the point(s)at1 pointwhich characteristic 1,listed in Table 1,evolved by marking“X”on the line(s)of thecladogram in the correct location(s).  \nSample Response:  \n·
