Figure 5.
Illustrations from H. Driesch (1892) showing effects of manipulating blastomeres of sea urchin eggs. His Figure 1 shows a normal 16-cell stage (copied from Selenka). Figure 2 shows a half-embryo from an 8-cell stage and Figures 3 and 4 half-embryos from a 16-cell stage. Figure 5 is a half-embryo at the blastula stage. These half-embryos developed into complete individuals. Figures 7 through 9 show blastulae in the process of dividing. These formed conjoined twins as shown in Figures 10 through 12. These results were interpreted as demonstrating regulative development.
