Trace and describe the formation of postnatal heart structuresfrom the primitive heart tube
Mammals and birds evolved from different reptilian lineages (therapsid reptiles and saurischian dinosaurs, respectively). Most reptilian hearts have three chambers (2 atria and 1 ventricle), yet the heart of both mammals and birds have four chambers.
Explain how these two groups ended up with similar structures.
Explain the evolutionary advantage of a four-chambered heart.
