a. Morpholgical species concept is based on the shape and structure of character traits on the species. This is applicable to both asexual and sexual organisms and is best when little is known on gene flow for the particular species. By looking at the three different frogs, the SV’s seem to be the same length. Therefore, the determination of different species must be done by looking at the leg length. The leg length is the feature that is morphologically different among the frogs. Looking at the graphs and comparing them to the length ratios show that C has a SV:Leg ratio of 1. From there, the comparison can be made of which ones have are different from C based on the differences between the curves and which ones are most similar. A and E have a less than 1 difference between each other making them a species. A and E are different from C with a large difference, greater than 1, making them two distinct characteristics. A and E also have a higher peak than C, C is broad. The ratios for B and D have a small difference between each other, meaning that they could be a species. The species are grouped based on the difference between the ratios and the peak that the curve has. The peak on B is much broader than D but they are close together with a little difference making them closer to being related than them being related to C. The SV: Leg ratios show that C, B and D, A and E are the different species groups.
b. The biological species concept is when species could or are interbreeding that are isolated from other groups. The mating calls of the frogs are a clear representation of biological species concept because some mating calls are similar, resulting in some species being able to reproduce with similar callings. But different cal...

...od suggests or tests a question on adaptation through comparing groups of species. Comparative method manipulates convergent evolution by using “natural evolutionary experiments” (Futuyma, 2013). A characteristic that comes about independently through a reoccurring pressure in the environment, the function of the characteristic, can most likely be found (Futuyma, 2013). These characteristics can be found through a model of the adaptive features that would be predicted to be found with the environment the species is subjected to (Futuyma, 2013). This meaning that all of the sperm from the various males will compete with each other to fertilize the egg. The one with the best and most sperm will most likely fertilize the egg. By looking at the characteristics scientists can find the use of a specific character trait and compare it to other traits of the same species.
