I loved Gould's book on the Burgess Shale. But this book arguing for a materialist view of evolution where random chance produces the marvelous variety of life we know, just didn't hold water for me.
I have been a science buff since childhood, and have read all kinds of science across the board. For me this was not science, it was a biased scientist putting forth an agenda based on a weak thesis and a weak argument.
I am not some sort of Christian "intelligent designer" (read "creationist"), but I also don't believe in a purely random material universe. There are mysteries to the universe that scientists don't even begin to address, but which philosophy always has. If science ignores basic philosophical questions, then it does not deserve to be called "science."
Questions:
Where did everything come from?
How could "something" come from "nothing"?
How could "everything" have always existed?
Gould does not deal with these questions, he simply begins with the Universe as we observe it, and life as a given. Then he tries to explain the emergence of life in all its diversity as "the Spread of Excellence." This is absurd on the face of it. Bacteria have existed since the earliest forms of life, and bacteria are "excellent," they are great survivors, great adapters, and our human bodies would not even function if we did not share some of the same genes as bacteria.
He makes the same mistake that better evolutionary scientists have already dismissed, which is the idea that life is always "improving" as it "evolves." This is false and it can be argued that some species have "devolved" into weaker, less "excellent" forms. We as humans like to see ourselves as the pinnacle of evolution, because we enjoy certain characteristics that are unique and clearly superior to other animals, but at the same time we are also "inferior" to other animals in many ways.
We appear to be successful because we seem to dominate the Earth. But ants also dominate the earth, and humans will probably be long extinct, as we are busy committing mass suicide, while the ants will continue on to survive and further diversify their species.
So Gould lost me on this one....
