Evolution of Biological Complexity

If you have a question about this talk, please contact Thomas Irving .

One of the most fundamental issues in biology is the nature of evolutionary transitions from single cell organisms to multicellular ones. Not surprisingly for microscopic life in a fluid environment, many of the processes involved are related to transport and locomotion, for efficient exchange of chemical species with the environment is one of the most basic features of life. This is particularly so in the case of flagellated eukaryotes such as green algae, whose members serve as model organisms for the study of transitions to multicellularity. This talk will summarize recent theoretical and experimental work addressing aspects of evolutionary transitions in the Volvocine green algae, which range from unicellular Chlamydomonas to Volvox, with thousands of cells. A key focus will be the nature of collective behaviour exhibited by the flagella of these organisms and the synchronization of those organelles.

The talk is free for members of BioSoc, and ÂŖ1 for everyone else.
