Andrew Knoll is the Fisher Professor of Natural History in the Department of Earth and Planetary Sciences at Harvard University. Andy's work straddles the line between the early evolution of life on Earth and our planet's environmental history. He has written numerous books on these subjects, most recently A Brief History of Earth: Four Billion Years in Eight Chapters (Custom House). In this episode, Robinson and Andy discuss when and how life arose on earth—and, just as importantly, what and how we know about it. Then they turn to some related topics, such as the diversity of microbial life on Earth and how it shaped our environment. They finish off with the possibility of life on Mars, as Andy was part of NASA's MER mission to Mars, which examined the soil and geology of Mars's surface through two rovers, Spirit and Opportunity.

In this episode, Xavier Bonilla has a dialogue with Andrew Knoll about the geological history of the earth. They discuss how light, gravity, dark energy, and dark matter explain the early origins of the universe and earth. They also talk about the various layers of the earth, zircons, tectonic plates, and how one defines life. They also talk about how geology can assist in telling the time of earth, why the geologic timescale is important, and the early Ediacaran and Cambrian periods. They also talk about the impact of climate change, human involvement, and many other topics.  Andrew Knoll is the Fisher Professor of Natural History at Harvard University.

Dr. Andrew Knoll is the Fisher Professor of Natural History in Harvard University’s Department of Organismic and Evolutionary Biology, where he studies ancient life, its impacts on the environment, and how the environment, in turn, shaped the evolution of life.  In recognition of the 200th anniversary of Charles’ Darwin’s birth and the 150th anniversary of the first printing of his book, “On the Origin of Species”, the American Society for Microbiology has invited Dr. Knoll to deliver the opening lecture, titled “Microbes and Earth History,” at the society’s general meeting in Philadelphia this year. Before the dinosaurs, before trees and leaves, before trilobites, there were microbes.  Vast, slimy layers of them covered the rocks and peppered the seas of the harsh, alien planet we now call Earth.  Those slimy cells were our ancestors, and they played a defining role in changing that once-barren moonscape into the world we see today: a planet covered with diverse, striving life, topped by an oxygen-rich atmosphere.  Dr. Knoll says he puts on his paleontologist’s hat and studies the fossil record to learn more about this ancient life, then he dons his geochemist’s hat to reconstruct Earth’s environmental history from the chemical signatures he finds in ancient sedimentary rocks.  He weaves these two stories together to figure out how life has transformed the planet and how the planet has influenced the course of evolution. In this interview, I talk with Dr. Knoll about what early earth must have looked like, his involvement with the Mars rover project, and how intelligent design concepts may well belong in high school curricula, but not in the context of science class.
