While environmental factors do contribute to phenotypic variation, this item does not provide a clear link to the evolutionary paradox of development, which involves the question of how a relatively small number of developmental genes can account for the vast diversity of forms and behaviors seen in organisms. The other items mention aspects of developmental genetics, variation in form and function, and the conservation of key developmental genes across animal groups, all of which are relevant to this paradox.
