Ringdoves on their nest

In 1949, the artist A. N. Komarov created a series of three paintings on commission of A. F. Kots (“Ringdoves on their nest”, “Stock doves on their nest”, and “Blue hill pigeons on their nest”) for the section “Natural selection theory” on the subject “Origins of domesticated species (hens and doves).” According to A. F. Kots, these works were supposed to demonstrate that “…it is from the blue hill dove that all domesticated doves ultimately originated,” because the stock dove and ringdove differ from the blue hill dove by their nesting manner.
