Abstract

A concept of evolution of ontogeny based on the original data on the comparative biology of Volvox development and published paleoclimatic data is presented. Previously, we have demonstrated that evolutionary reorganizations of asexual development in Volvox are related to the changes in the rate, diel rhythms, and light/dark control of cell divisions. Here, we propose that such rearrangements could take place during much of Cenozoic time (e.g., in Eocene and Miocene) as adaptations to short and warm winter day in high latitudes. This proposal is confirmed by experimental data on culturing Volvox species with different types of development under short photoperiod.
