I haven't found one, so I'll try to summarize here:

"Prokaryotic life probably came to Earth from somewhere else. It was successful and made Earth into a finely tuned paradise. (A key point here is the role of life in preserving liquid water, but there are many other points, the author is a scientist and likes to point out improbable coincidences.) Then a tragic accident caused individualistic eukaryotic life to appear, which led to much suffering and death. Evolution is not directionless, its goal is to correct the mistake and invent a non-individualistic way of life for eukaryotes. Multicellularity and human society are intermediate steps to that goal. The ultimate goal is to spread life, but spreading individualistic life would be bad, the mistake has to be corrected first. Humans have a chance to help with that process, but aren't intended to see the outcome."

The details of the text are more interesting than the main idea, though.
