Moriarty Science Seminar: Molecular Paleobiology of Early Life on Earth
March 8, 2021, 12:00 pm - 1:00 pm
R.W. Moriarty Science Seminar Presents: Molecular Paleobiology of Early Life on Earth
Speaker: Betül Kaçar
Only one record of life exists, but what does that tell us about life’s existence elsewhere? Will we recognize “life” when we see it? Are there characteristic chemical properties that would be common to all forms of life, or can they differ substantially? What are the significant historical innovations of life that shaped the life we observe today?
In this lecture we will travel back in time and take a journey across the history of life on Earth from a molecular perspective. Betül Kaçar will discuss the emergence of essential metabolisms, their evolution across billions of years of planetary evolution, and how molecular innovations were impacted by significant changes in the environment, including the Great Oxidation Event.
