Article Abstract:
Thomas Kuhn's contribution to the philosophy of science was his book, 'The Structure of Scientific Revolutions,' where he opposed the traditional idea of 'scientific progress.' His idea had a favorable impact on the scientific community. However, since these were drawn from chemistry and physics, questions abound as to whether the Kuhnian revolution had an impact on biology as well. Analysis shows that scientific revolutions in biology, such as the Darwinian and Mendelian revolutions, fail to match the Kuhnian paradigm as it was able to reject an outmoded theory of scientific progress.

Article Abstract:
Technical terms often take on new connotations with time, regardless of the precision of their original definition. As a consequence of these subtle changes, terms frequently become ambiguous and give rise to endless debates whenever they are applied. The field of developmental biology is particularly susceptible to this phenomenon, as seen in terms like 'embryonic determinant,' 'morphogen' and 'organizer.' To avoid such an occurence, researchers should always be careful in defining terms used in their publications and always use operational definitions.
