I agree with Trotman's main claim that the earliest forms of life on earth must have been irreducibly complex. Irreducible Complexity does not imply a designer, because it describes the state of a system, not its origin. Trotman argues for an extraterrestrial origin of life without attacking neo-Darwinism. The Feathered Onion is far more than a defence of panspermia. Trotman's book is a courageous, ingenious and successful attempt to identify irreducible complexity as the essence of life, without resorting to intelligent design.
The book itself is a pleasure to read, well designed, and accessible. High value, low price.
