Four billion years ago, the infant Earth was a seething cauldron of erupting volcanoes, raining meteors, and hot noxious gases, totally devoid of life. But a relatively short time later - only 100 million to 200 million years - the planet was teeming with primitive organisms.
What happened? Now you can find out - in a series of 24 vibrant lectures from a leader of the NASA - supported team studying the origins of life in the universe and also one of the nation's foremost science educators. The lectures take you from path-breaking experiments in the 19th century that proved the molecules of life to be no different from other chemicals, to our increasingly sophisticated modern understanding of just how the chemistry of life works, to the near certainty that the 21st century will see spectacular and unpredictable developments in our understanding of how life began. For all its familiarity, life is an elusive concept that is hard to define, much less explain. These lectures show how scientists are systematically building a picture of the process by which those chemical reactions on the early Earth eventually led to the first appearance of the DNA-protein world that remains the fundamental basis of all life today. And you'll join them as they probe for evidence of life beyond our planet.
Crammed with fascinating experiments, surprising results, heated debates, blind alleys, and promising leads, the investigation of life's origins is a mystery story in the truest sense - one in which the clues are slowly adding up but the solution is not yet in hand.

Can't seem to get enough of Robert Hazen's courses, so I listened to this great topic a second time, learning more this time around about the origins of life. I'm impressed he remains so enthusiastic about his own beliefs, but presents competitive theories in a very unbiased way. Well worth my time.
I have an intense interest in the subject matter.
This is the best book on the subject I have "read" so far.
This is a comprehensive overview of the proposed theories in the search for the plausible scenarios for the origins of life. Dr. Hazen brings the subject to life (pun intended) by not only talking about the science, but also the personalities, the politics and the process of scientific exploration.
This book is a worthwhile read for scientists,but is still very accessible to the lay person as well.
The Professor giving this lecture is a very good public speaker. I like the way he makes science into a story. He makes the laboratory experiments come alive.
The lecture is interesting in that it sheds light on all the different theories of life's origins and really allows you to stand back from your human perspective paradigm and see that we were once and still are chemistry!
This audiobook was done very well and was enjoyable to listen to start-to-finish.
Going over the Miller-Uri experiments was interesting. I've heard much about these experiments, but not to the detail that Dr. Hazen provided, along with the impact that these studies have had on other "origins" work.
Hearing the lecture gives the listener an idea of inflections and emotion that goes into the material, rather than reading from a book.
"Discover the possibilities of life's chemical origins"
This was a great lecture series on the origins of life. As the title indicates, this series sticks with molecular origins ONLY and does not really move beyond unicellular life (bottom up approach). Having a background in chemistry/biochem is certainly helpful, but overall I found this to be an interesting and relevant series on covering the many theories of life's origins.
Pros: Dr. Hazen covers many of the theories held by a variety of disciplines for life's origins in a neat, organized manner. He really drives home the point that there are MANY ideas on how life arose verses the misconception that some scientists feel there is only one means by which life could have begun.
Cons: Without a basic understanding of chemistry, most people would have a hard time following this lecture.
Bottom line: certainly worth a listen for anyone interested in getting a 10,000 foot perspective on the many ideas as to a natural means for emergence of life on earth.
Hazen goes over all the major facets of this field, breathing life into the theories, the speculations, and the experiments. His detailed explanations of key experiments does require more attention than casual listening, but it's worth the effort.
Yet another gem of a lecture course from Robert Hazen. A mind expanding tour de force.
The Cambrian Explosion.
First rate presentation of exciting material!
