simple heart-like cells to those with complex four-chambered hearts, it has been theorized and proven that expansion of this regulatory network by adding new transcription factors is a major force for the heart to evolve new structures.1,2 How-ever, the addition of new transcription factors can only be a part of the mechanism underlying the formation of complex hearts. The transcription

lineage of vertebrates [12]. The lamprey is considered to have four heart chambers, which are the sinus venosus, atrium, ventricle, and conus arteriosus [13]. This is similar as to the zebra?sh heart, which contains four chambers - the sinus venosus, atrium, ventricle, and bul-bus arteriosus. Lamprey hearts also are valvular pumping systems, containing valve lea?ets between chambers [14 math games for high school pdf 3 Figure 17.8 Subphylum Cephalochordata Called lancelets: ~45 species Body laterally compressed and ?sh or tadpole-like All four chordate characteristics persist throughout.

Abstract. Lamprey is one of only two living jawless vertebrates, a group that includes the first vertebrates. Comparisons between lamprey and jawed vertebrates have yielded important insights into the origin and evolution of vertebrate physiology, morphology and development.
