In the book published in 1866, "General morphology of organisms" reveals this concept as the science of the interaction of living organisms with each other and with a cutoff medium. Assumed the existence of an intermediate form between the monkey and man - the discovery of the Pithecanthropus confirmed his prediction.

He justified that for every single species in the economy of nature only the total number of places is available - ecological niches. And in one area there can be more individual animals, the more diverse their nature. He formulated a biogenetic law, according to which in the individual development of the organism the main stages of its evolution are actually reproduced.
