- The best argument for how an unprotected species can evolve to mimic a second protected species (distasteful or noxious) and thus obtain protection is by A. Random changes in the appearance of the unprotected species that lead to increased fitness due to greater similarity with the protected species B. Individuals deciding that they need protection and mutating to look like the protected species C. Individuals changing their diet to increase pigment production to look like the protected species D. Natural selection for more advanced traits that are better to the inferior traits of organisms that do not look like the protected species E. Behavioral modification of the unprotected species to act like the protected speciesarrow_forwardConsider the graphic that is presented and depicts the end-point for the following scenario. At some point in the past, species A resided as a large population entirely within a rectangular geographical area. The population became divided into two isolated populations when, during a major earthquake, a mountain range arose and disrupted gene flow. Over time, the two new populations evolved independently from one another, yielding species B and C. The population comprising species C became divided into two isolated populations when another earthquake created an escarpment that disrupted gene flow. Over time, these two new populations evolved independently from one another, yielding species D and E.Imagine that you were to arrive to the region long after species D and E had evolved, completely oblivious to the scenario that is described above; survey the region for living species in this group; and conduct a cladistic analysis on those species.
