Two ways for interpreting Driesch's law: 'Positional information' and morphogenetic fields

摘要

The late Lev V. Beloussov wrote a 2005 textbook The Foundations of General Embryology which is available in Russian. In 2003 he prepared an excellent, annotated translation of the part of his manuscript for this book on distinguishing positional information models from morphogenetic field models of embryogenesis, which is reproduced here verbatim. He concluded: "... the PI [positional information] concept has no predictive value, and cannot be thus regarded as a scientific theory".
