The Ecology and Evolutionary Biology Department has been working hard and monitoring, as well as planning, for COVID-19/Coronavirus and the safety of the UCLA community. We understand that we live in very uncertain times and, with news about the virus changing frequently, we appreciate your cooperation. Please know the department is committed to working in everyone’s best interest—students, faculty, staff, and community at large.

With this, our Fall 2021 Seminar Series will be held in-person and virtually.

We appreciate your understanding at this time.

" Behavior is a Motor and Brake for Evolution "

One of the most striking patterns of evolution is its uneven tempo across the tree of life. Whereas some traits and lineages diversify rapidly, others appear to remain inert over millions of years. But why is this so? What allows some features to achieve evolutionary overdrive, and why do some traits appear to straddle evolution’s slow lane? I explore this question by focusing on one of evolution’s key architects: behavior. I illustrate how organisms are not the passive targets of selection; rather, through behavior, they can be the agents of selection. Using Caribbean Anolis lizards as a model system, I reveal the signatures of behavior at both micro- and macroevolutionary scales and illustrate the constraints on this phenomenon. Behavior has the power to slow and hasten evolution and, on occasion, it does both simultaneously.
