Recognizing Species Traits This is a two-part test. First, match each of these Oncocyclus species with its name: I. haynei, I. iberica, I. lortetii.
One, and only one, of these is known to be an ancestor of each of the following three arilbreds. The other two are not found in any of these three pedigrees, tracing back to species and C.G. White stock of unknown parentage. Can you guess which species is the common ancestor?
