Please join us on January 22nd as the Directorate for Biological Sciences welcomes Dr. Michael Lynch of Arizona State University and Director of the Biodesign Center for Mechanisms of Evolution for his Distinguished Lecture titled, "Evolutionary Origin of Cell Biology’s Scaling Laws.”

The following abstract provides insights into the lecture topic:

Many well-known power-law scaling relationships have been discovered that apply across the Tree of Life for various aspects of molecular biology, physiology, genome structure, and intracellular structure. The diverse explanations for such patterns are controversial, but almost always seek shelter in natural-selection scenarios. However, although natural selection may be the most powerful force in the biological world, it is not all powerful. Ultimately, the power of random genetic drift determines what selection can and cannot accomplish. The drift-barrier hypothesis provides a potentially unifying explanation for a diversity of biology’s scaling laws, including the evolutionary diversification of the mutation rate, aspects of gene structure and genome architecture, and maximum cellular growth rates. This broad set of observations, bolstered by theory, implies that the population-genetic environment imposes a fundamental constraint on the paths that are open vs. closed for evolutionary exploration in different phylogenetic lineages. Integration of biology’s three engines of quantitative theory – population genetics, biophysics, and systems biology – will be required for the establishment of a formal field of evolutionary cell biology.
