Cortical inheritance
Cortical Inheritance or structural inheritance was discovered by Tracy Sonneborn during his study on protozoa in the late 1930's. The mainstream scientific community believes that all inheritance is passed on via the genes in the nucleus of a cell. Sonneborn, however, demonstrated during his research on Paramecium that the structure of the cortex was not dependent on genes or the liquid cytoplasm but in the cortical structure of the surface of the ciliates. Preexisting cell surface structures provided a template that was passed on for many generations.
