Vertebrate circulatory and respiratory systems

Assignment Help Biology
Reference no: EM132412697

Vertebrate circulatory and respiratory systems are tightly integrated, but when we examine non-vertebrate chordates, we typically find either both systems are absent or there is a circulatory system without a specific respiratory system. This raises the question of how it is possible for these two separate, non-homologous systems to evolve such a connection when they were clearly separate to begin with. Develop and present a hypothesis to explain how it is possible for such integration to evolve using the phylogeny, biophysics, and evolutionary forces course themes. For each theme, explain what type of evidence you could look for to support the ideas based on that theme and why that evidence would provide support to your hypothesis.
