Trace the evolution of the circulatory system through animals. From sponges up through arthropods ?
Would having two or more hearts be
adaptive for vertebrates? Why do you think
that invertebrates have evolved multiple
hearts but vertebrates have only one?
A four-chambered heart, with a complete septum between the left ventricle and the right ventricle, makes the warm-blooded condition possible for all of the following vertebrate groups except:
modern placental mammals (like the beaver)
modern amphibians (like the frog)
modern monotremes (like the platypus)
modern birds (like the bald eagle)
modern marsupials (like the kangaroo)
