Origination Of Organismal Form

Origination of Organismal Form: Beyond the Gene in Developmental and Evolutionary Biology (ISBN 0-262-13419-5) is a book published in 2003 edited by Gerd B. Müller and Stuart A. Newman. It explores the multiple factors that may have been responsible for the origination of biological form in multicellular life. These biological forms include limbs, segmented structures, and different body symmetries.

The book explores why the basic body plans of nearly all multicellular life arose in the relatively short time span of the Cambrian Explosion. The authors focus on physical factors other than changes in an organism's genome that may have caused multicellular life to form new structures. These physical factors include differential adhesion of cells and feedback oscillations between cells.

The book also presents recent experimental results that examine how the same embryonic tissues or tumor cells can be coaxed into forming dramatically different structures under different environmental conditions.

One of the goals of the book is to stimulate research that may lead to a more comprehensive theory of evolution.
