In Spadefoot toads a change in the environment can change the developmental pathway so that the carnivore morph (form) develops rather than the omnivore morph. Which of the following best describes this process?
a. The environment mutates genes leading to a genetically different form
b. The environment directly alters developing cells without affecting genes in any way
c. The environment affects the expression of genes involved in development of the tadpole
d. The environment results in the evolution of a new species
e. The environment creates new Hox genes
