Thompson wrote On Growth and form in the maturity of a career that lay somewhat outside the mainstream of the biological sciences of his day. His writings were a large contribution for the study of morphology. On Growth and Form is essentially an attempt to establish a concept of organic form based upon the physical and mathematical laws governing the development and function of organisms. He demonstrates in this chapter that how organic forms once put in a Cartesian grid can change forms in the same species and how this method could be used to find missing parts in the series of relative species

During the debate in the class we found the book is more of a concept and basically starts with the theory of transformation and is solidly based upon the laws of Newtonian Physics. All the experiments D’Arcy conducted were in 2D and not in 3D and gives a mathematical approach to the biological forms. He tries to show how the relationship between similar species is still there but changing their coordinates and the position of the parts changes. It’s a form finding method found over 100 years ago and gives us an idea of multiplicity during that era. Topology has been explained as a concept here with no real results. It’s a relation of a part to a whole. Read More »
