In the late 1960s, Robert Paine conducted landmark studies on diversity in the rocky intertidal zone, comparing the species diversity in control plots with diversity in experimental plots, from which he removed sea stars, the top predator. After 5 years, 15 species of intertidal invertebrates lived in the control plots, while the experimental plots were dominated by only two species, a mussel and a barnacle. In the last few years, a disease has emerged that is decimating the sea star...

What was the major observation from previous studies that lead Yamanaka (and others) to believe that it would be possible for a somatic cell to be re-programmed back into a pluripotent stem cell?
