Molecular and cell biology can be understood and appreciated only in the light of their relations to the whole organism. However, in recent years it has become fashionable to reduce or to eliminate altogether laboratory time allotted for organismic biology. In this program, students prepare and then study cross sections of planaria, earthworm, lamprey (larvae), and tadpole. The laboratory guides emphasize hierarchies of animal complexity and the similarities and differences between the invertebrates and vertebrates.
