Amphibians have gills when they are young or they breathe through their skin. Adult amphibians either have lungs or continue to breathe through their skin.Amphibians have three ways of breathing. The first is with gills, seen on tadpoles and salamanders that do not leave the water. The second isâ¦.
Homology involves the theory that macroevolutionary relationships can be proven by the similarity in the anatomy and physiology of different animals. Since Darwin, homology has been cited in textbooks as a major proof for evolution. A review of the literature on homology indicates that the theory does not provide evidence for evolutionary naturalism, and that the common examples of homology can be better explained by Creation.
Homologous structures are body parts that are alike because the species in question share a common ancestor. These structures may serve the same or different functions.For example, the wing of a bird and the arm of a human serve very different functions, but are considered homologous structures because of the evolutionary relationship between birds and humans.tructures that are embryologically similar, but have different functions, are called homologous structures. Though these animals look different, a comparison of homologous structures indicates that they are quite similar. This suggests that these animals evolved from a common ancestor.   by: Lameace[=.
