   What events in pregnant woman underlie twins formation? What do zygosity, chorionicity and amnionicity depend on? It seems that the answer is very clear. As early as in 1955, the works by G.W. Corner were published, which served as the basis for proposing the traditional model of twins formation, still remains widely acknowledged. But whether is everything so obvious? In order to answer this question, it is necessary to go back to the roots and understand of how the overall idea about fertilization and formation of multiple pregnancies has evolved since the XVII century till the present time.

   В результате каких процессов в организме беременной женщины происходит образование двоен? От чего зависит зиготность, хориальность и амниальность? Кажется, что ответ предельно ясен. Еще в 1955 г. были опубликованы работы американского эмбриолога Дж. В. Корнера, на основе которых была сформирована традиционная модель формирования двоен, которая по сей день пользуется популярностью. Но так ли всё очевидно? Для того чтобы ответить на этот вопрос,необходимо обратиться к истокам и понять, как же эволюционировало представление об оплодотворении в целом и об образовании многоплодной беременности, начиная с XVII века до настоящего времени.
