The ideas of such prominent geneticists as Vries, Cuenot, Guyenot, Johannsen, Tchetverykov, Philiptchenko are considered. The conjectures on the specific mechanisms of evolution above the species level may be found in many of them. The very terms of micro- and macroevolution have been proposed by Philiptchenko in 1927. But he denied any role of genetics in puzzling of the higher taxa origin, the letter being connected him with sexual sells plasma. The actual significance of Goldschmidt's conception about systemic mutations is mentioned.
