Speaker: John Clarke is research fellow at the chair of entomology, Department of Zoology, Tartu University. He explores evolution, including diversification, using fishes as model systems.
Title of the talk: Polyploidy, historical expectations and habitat shifts: revealing macroevolutionary dynamics underpinning half of vertebrate diversity
Time: Thursday, 11. April 2018 at 15.15
Place: Tartu, Lai 40-218 (Vaga auditorium)
Summary: Why are some groups extremely diverse in morphology, while other groups vary little in morphology? To address this fundamental question, I use actinopterygian fishes (~33000 species today) as a model system, testing classic expectations regarding their morphological evolution through time, ranging from genome duplication to the role of habitat type.
