Outline of Final Research Achievements

There have been few experiments that understand body-structures of the various animals in biology class in high schools. In the present report, a new experiment has been developed to understand the typical body structures with the phylogenetic tree, using a brief hand-made section of frozen tissues.
The sponge, the hydra, the planarian, the earthworm, the amphioxus and the larva of newts had the different body structures each other, showing the importance of cell differentiation, the germ-layer, the gut, the coelom, the notochord and the neural tube. Thus, it was shown that the present experiment was good for understanding the animal kingdom totally.
