Lecture Title: TBD

Andrew has made important contributions to evolutionary protistology and was the founding Director of the Centre for Comparative Genomics and Evolutionary Bioinformatics at Dalhousie University (now the Institute of Comparative Genomics, icgenomics.ca).  Over two and a half decades, Andrew and his collaborators have employed comparative genomic, phylogenetic, and other ‘omic’ approaches to clarifying how eukaryotic cells and their symbiont-derived organelles originated and diversified in the past ~2 billion years.  Other topics of particular interest include adaptations to low oxygen conditions in anaerobic protists and clarifying the role of lateral gene transfer in these adaptations, as well as the development methods and models for ‘deep-time’ phylogenetic inference. Andrew has published more than 200 peer-reviewed articles in these fields and has received numerous accolades for his work, including being appointed as a Tier I, Canada Research Chair,  and receiving an award of a Fellowship in the Royal Society of Canada.

Lecture Title: A Paleontological Perspective on the Early Evolution of Eukaryotes (Mostly Protists)

The fossil record provides the only direct evidence for us to assess the diversity and evolutionary dynamics of early eukaryotes. In this presentation, I will summarize recent advances in the study of eukaryotic fossils from the Proterozoic eon (2500-539 million years ago, Ma), with a focus on the evolution of eukaryote diversity and the origins of major eukaryote clades. Eukaryotes first appeared in the fossil record in the Paleoproterozoic, concurrently with or shortly after the ~2400-2300 Ma Great Oxidation Event. For much of the Mesoproterozoic (1600-1000 Ma) and early Neoproterozoic (1000-720 Ma), the diversity of eukaryotes increased slowly and remained at a relatively low level; this period roughly corresponds to the Boring Billion, - a geological period characterized by relative quiescence in geodynamics, indicating long-term equilibrium of the Earth-life system. However, it is during the Boring Billion when crown-group eukaryotes first appeared in the fossil record and major eukaryote groups diverged, including the Archaeplastida (e.g., Rhodophyta and Viridiplantae), Opisthokonta (e.g., Fungi), SAR or Harosa (Rhizaria and possibly Stramenopila), and Amoebozoa. Despite their early divergences, these eukaryotes apparently did not leave a large ecological footprint in the Mesoproterozoic Earth-life system. The Cryogenian Period (720-635 Ma) following the Boring Billion served as a major divide in eukaryote evolution. After Cryogenian snowball Earth events, eukaryote diversity rose rapidly and featured major diversification and extinction events in the Ediacaran Period (635-639 Ma). It is during the Ediacaran Period when animals diverged and diversified, along with the quick rise and fall of several morphologically distinct groups of unicellular and multicellular eukaryotic groups. The currently available and emerging data from paleontology, phylogenomics, and geochemistry allow us to establish a holistic understanding of the interaction between life and Earth during the Proterozoic eon, - a formative age in the history of our planet.

Keywords: Proterozoic, eukaryotes, fossil record, diversity, evolutionary dynamics

Shuhai Xiao is a paleobiologist and geobiologist who studies the interactions between the biosphere and its environments at critical transitions in Earth history, particularly during the Ediacaran-Cambrian transition.

Lecture Title: Adaptive Evolution in Protists: Diatoms as a Test Case.

Oceanic photosynthetic protists such as diatoms contribute at least 20% of global primary production. Yet, how their genomes evolve under conditions of natural selection to cope with environmental change of the upper ocean has barely been investigated. However, this fundamental knowledge is not only essential to identify mechanisms of how they adapt, but it may also be used to investigate and to predict the evolutionary response of important primary producers to global climate change. To address this knowledge gap, this plenary lecture will introduce the concept of adaptive evolution and how it can be applied to identify evolutionary mechanisms that shape the structure and function of protist genomes using model diatoms as a test case. By applying the approach of experimental evolution to wild-type and genetically modified (CRISPR/Cas genome editing) diatom strains under conditions of natural (temperature change) and artificial selection (DNA mutagen), our work not only revealed mechanisms of adaptive genome evolution in diatoms, but it also has shown that there are hotspots of evolution in the genome depending on the selection pressure imposed. Furthermore, the geography of chromosomes impacts the rise of genetic variants involved in adaptation and population differentiation. If the mechanisms of adaptive evolution in diatoms are conserved across diverse protists and possibly other eukaryotes remains to be identified.

Keywords: Adaptive evolution, diatoms, chromosomes, DNA repair, natural selection

He obtained his MSc (1998) in Biology with emphasis on Biological Oceanography at the Christian-Albrechts University in Kiel (GEOMAR) and the PhD (2003) at Bremen University (AWI), Germany. Before joining the University of East Anglia (UEA) in 2007, most of his PostDoc research was conducted with a fellowship from the German Academic Exchange Service (DAAD) in the School of Oceanography, University of Washington (E.V. Armbrust lab) in joint cooperation with the Biotechnology Center, University of Wisconsin (M.R. Sussman lab), USA. Before he was promoted to Professor (Personal Chair) in 2014, he was Reader (2012-2014) and had a Research Councils UK (RCUK) Academic Fellowship (2007-2012).

Lecture Title: Evolution and diversity of mitosis

Despite the fundamental role of cell division in the propagation of cellular life, eukaryotes have evolved a diverse range of strategies to remodel and partition organelles and cellular contents in mitosis. What drives the evolution of mitotic mechanisms? Bridging lab and field expeditions, we use a range of microbial model systems, comparative genomics, imaging and experimental evolution to probe mitotic diversity on short and long evolutionary timescales. I will present our recent work on the rewiring of mitotic mechanisms in deep-branching holozoans, green algae, and slime moulds, and finally our initial efforts to generate a eukaryotic mitotic atlas using expansion microscopy.

Gautam is an evolutionary cell biologist and Group Leader at the European Molecular Biology Laboratory (EMBL). His research group investigates the evolution and diversity of mitosis and nuclear remodelling across eukaryotes using a combination of comparative cell biology, experimental evolution and genomics in multiple microbial models. Gautam started his group at EMBL in early 2021, after a postdoc at UCL with Buzz Baum. Gautam holds a PhD from Stanford University and a research MSc. from NCBS in Bangalore. Gautam is an ERC Investigator (2023-2028), an EMBO Young Investigator (2025-2028), a FEBS Excellence Fellow (2024-2026); a previous holder of a Marie-Sklodowska Curie postdoctoral fellowship (2017-2018) and a Stanford Graduate Fellowship in Science and Engineering (2009-2012).
