Step back in time
As part of the outreach component of our Total Evidence Dating (TED) Project, we planned to create a series of video lessons about plants in Deep Time, targeted at non-specialist audiences. These videos are produced by TED-PI Nathalie Nagalingum, together with the California Academy of Sciences (CAS) outreach team. The first two videos illustrate key aspects of the relationship between Earth and its green continents: how plants changed our planet and how climate change influences today's plants. The one that the CAS outreach team is currently working on, focuses on the TED project itself.
How did plants change our planet?
Botanist Nathalie Nagalingum explains how, more than 400 million years ago, early plants played a notable role in adjusting Earth’s physical surface, as well as our planet’s climate. She meets with paleobotanist Cindy Looy to discuss the evidence that scientists currently have to support her story. Subtitles are available in Spanish, Chinese, and many other languages!

Did Past Climate Change Influence Today's Plants?
How does the environment affect species? Botanist Nathalie Nagalingum and plant physiologist Jarmilla Pitterman (UC Santa Cruz) share the history of juniper and cypress trees, and how they evolved during a cold and dry period in Earth's history. They also explore how current climate change might affect these trees and other plants.
