Dr. David McKay, Chief Scientist for Astrobiology at the Johnson Space Center, lectures on his scientific experience with meteorites, more specifically ALH 84001.
Astrobiology is a new meta-discipline which combines astronomy, biology, chemistry, philosophy, and physics in an effort to study the current state of life in the universe.
In the Stanford Astrobiology Course, lectures follow a, more or less, linear path from the Big Bang all the way to the development of complex life and, finally, space exploration. The course explains how evolutionary principles have operated at the macro, and micro, level ever since the birth of the universe we reside in today.
