Abstract
By means of geometric morphometry comparing recent and subfossil ants Formica lemani in West Siberia, clear morphological changes in the structure of head capsule were revealed. These changes occurred during the recent several hundred years; they are connected not with taphonomic rearrangements but with morphogenetic ones. The rate of microevolution changes turned out to be unexpectedly high because during only several hundred years the divergence degree of recent and subfossil ants has approached the subspecies level.
