Question: If you used the presence or absence of saber-shaped teeth to construct the phylogeny of mammals and compared it to Fig. 2, what would be the outcome? You could not infer relationships because saber-teeth are uninformative. You would infer the same relationships among mammals. You could not infer relationships because not all mammals have saber-teeth. You would infer incorrect relationships because saber-teeth are an example of homoplasy. You would infer the incorrect relationships because saber-teeth are an example of a reversal. Need Assignment Help?
