The Laboratory of Evolutionary Morphology was established in the 1960s by Academician A.V. Ivanov, Lenin prize winner. Extensive comparative investigations of invertebrate anatomical and histological systems are carried out using modern methods.
Representatives of the lower invertebrates (such as lower worms, molluscs, pogonophorans, lower chordates and others), important for the development of the animal kingdom system, are the main objects of study.
Examinations of digestive tract regulatory systems involve all major metazoan groups. Morphological laws of the evolution, including conditions and evolutionary pathways typical of different phylogenetic branches are elucidated.
