Just over 4 and a half billion years ago, a cloud of gas and dust came together to form our planet. Since then, it has undergone massive change. In HHMI’s 2012 Holiday Lectures on Science, three leading scientists will explore the history of life on Earth and the forces that have shaped, and will continue to shape, our ever-changing planet.
Andrew H. Knoll of Harvard University will use the fossil-record geochemistry to explain the history of life on Earth, as well as discuss his exploration of the geology and possibility of life on Mars. Naomi Oreskes of the University of California, San Diego, will present past scientific models of the forces responsible for shaping the physical features of our planet and describe the current understanding of plate tectonics. Daniel P. Schrag of Harvard University will discuss climate change over geologic time and explain how understanding the past can help us comprehend the impact of our activities on current and future climate.
The Holiday Lectures will take place November 15–16, 2012, at HHMI headquarters in Chevy Chase, Maryland. You can sign up to view a live webcast at www.holidaylectures.org.
