Review the evidence below for each hypothesis, then, using that evidence, explain whether they should be classified as distinct or the same species based on each species concept. Then, using the overall evidence, decide whether to classify them as the same or different species. Genetic Information (In the Species Concepts lab, we used a "controversial" 10% cutoff. A more realistic cutoff might be 1%. Let's use a 1% cutoff for this activity.) Sequence Differences Baltimore Oriole vs Black- backed Oriole Cytochrome b 0.26% Control region 0.74% 2A. Based on the genetic information above, should the Baltimore Oriole and Black-backed Oriole be classified as one species or two species?arrow_forwardRefer to the phylogeny below.
