As a child via my godfather, Professor Sulo Toivonen, I was exposed to his research with salamanders. In the summer time Sulo used to collected embryos from ponds to conduct experiments how to construct a new body plan. In his lab, I had a change to look at the embryos, smell the taste of the lab, the microscopes, and the research tools. I learned that a process of cell communication was a key to emerge the morphological structures throughout the nature in all species. I have studied these questions ever since.
