Hi Percy,
I do not have a scanner. I do know people who do, however, and I will scan some pages as soon as I can.
In the meantime, here's the passage I was referring to.
In the 1950's, American chemists Stanley Miller and Harold Urey tried to answer that question by simulating conditions on the early Earth in a laboratory setting. They filled a flask with hydrogen, methane, ammonia, and watter to represent the atmosphere. They made certain that no microorganisms could contaminate the results.Then, they passed electric sparks through the mixture to simulate lightening.
The results were spectacular. Over a few days, several amino acids-the building blocks of proteins-began to accumulate. Miller and Urey's experiments suggested how mixtures of the organic compounds necessary for life could have arisen from simpler compounds present on a primitive Earth.
This book was written by Ken Miller and Joe Levine by the way.
Anyway, what is this experiment doing in a 2006 Biology book? Especially alone in a 2006 Biology book. There is no mention of any other experiments relating to life on early Earth in this book. Does that mean there are no such experiments? If not, why are'nt they in the text? If so, why have these experiments not been performed?
