Darwin thought that the divergence/change in structure of species within the same area was the same as the physiological division of labor in the organs of the same body. For edwards, division of labor reflected divine order of life from simple to complex. Darwin thought physiological division of labor= ecological division of labor: when animals are physiologically diverse, their body parts have different functions, this causes variation, and they acquire different specialized niches so there is less competition for resources.
