Silica in the Oceans and Our Understanding of Early Life

Linda Kah, professor in the UT Department of Earth & Planetary Sciences, will present “Silica in the Oceans and Our Understanding of Early Life,” Friday, February 14.

The mineral silica occurs as the body elements of skeletal marine plankton. But what was the behavior of silica prior to the evolution of the skeletal organisms? Professor Kah will explore why silica mineralization is considered the “holy grail” in efforts to understand the evolution of the earliest life on Earth. She will discuss how silica mineralization may have occurred in marine systems prior to the evolution of skeleton-producing organisms.

The UT Science Forum takes place Fridays from noon to 1 p.m. in the Thompson-Boling Arena Cafe (located at 1600 Phillip Fulmer Way), Room A. Guests are encouraged to bring their lunch or purchase it from the arena. Each presentation is followed by a Q&A. The event is free and open to the public.

We have temporary parking passes available for our guests who do not have UT parking passes. An RSVP is required for the pass. To request a pass, please visit us online at
