This is a good popular work that focuses on the more interesting/less talked about side of the debate. Dr. Sermonti, a famous and well-respected geneticist, speaks with much eloquence about the anomalies in nature that throw a monkey-wrench into Darwin's theory. However, he's not a creationist; rather, it seems that he takes more of a Platonist's view of biological organisms.

Such topics include:

A. The fact that organisms with varying complexity do not have proportional genome sizes. If neo-Darwinian evolutionary theory (NDET from now on) were true, shouldn't mammals have more DNA than amphibians, mollusks, or flowering plants? You would think so if NDET were true and an increase in DNA meant an increase in complexity, but you'd be wrong. They vary *widely*.

B. The sudden appearance and stasis of species in the fossil record. Though this is frequently discussed in other books in the origins debate, it is always good to throw it in.

C. How some animals seem not to be fitted for their environment, but rather, they seem to be works of art. As Sermonti put it: "In fish the colors can be bright and resplendent, even among species that never see the light of upper regions, but their patterning bears no relationship to internal structure; the colors just seem to be put there like paints on an artist's palette" (p.58). There are other things mentioned such as the beautiful mathematical shape of the mollusk's shell and the innate knowledge of some birds to know their bird-song without being taught it.

D. The fact that the same genes (such as hox genes) can create different structures in different animals. For instance, a cat's "eye" genes that are transferred to a blind fly's egg will create the multi-faceted eyes in a fly.

I found reading the book very enjoyable. One of the points that I liked most was how Giuseppe Sermonti shows that there is no determinism of DNA in relation to some differences in body structure and function. Evidently fundamentalists will label the book creationist garbage. But that does not matter. The dogs bark but the caravan passes.

Format: Paperback
I find the structure of this book to be surprising. Most of what Mr. Sermonti has to say is fairly irrelevant to the question of the veracity of NeoDarwinian evolution. He makes a strong case that there are other specific structures in living organisms beside DNA that must be carefully reproduced for life to reproduce. How this is consequential is beyond me. Reproduction is reproduction. Whether it is DNA or prions, if there is accurate reproduction, with rare but existing reproduction error (mutation), then the raw material for NeoDarwinian evolution exists.

However, Mr. Sermonti presents data that is fundamentally contrary to NeoDarwinian evolution. If his data is correct, the only logical conclusion can be that mutation + natural selection, with all of it's subtleties, cannot adequately explain this data. If it cannot adequately explain this data, then it is not the complete answer to the question of how all the varieties of life came to be.

Some have questioned whether NeoDarwinian evolution is falsifiable. Certainly there have been many expectations from simple theory which have found to be too simplistic.

* Scientists expected gradualism to render in the rock record, and concluded that punctuated equilibrium was a better description of the rock record. Rather than finding the theory to be false, evolution adapted to absorb this new data, to the point where punctuated equilibrium is now considered to be a characteristic of NeoDarwinian evolution.

* Studies of animals with similar characteristics were found to have fundamentally different heredities. Seals and Manatees, for instance, are both primarily aquatic animals that have a lot of similarities, but do not have a common ancestry.

Discovery fellow and editor of the prestigious Italian biology journal "Revista de Biologia," Giuseppe Sermonti explains why evolution resembles a "paradigm" more than it does an explanation. Scientists assume that the theory and its implications (such as universal common descent) are true, but no one can ever explain the details of precisely why it is. According to Sermonti, naturalistic theories of biological origins are science-stoppers.

Sermonti explains that biology has advanced greatly when naturalistic theories of biological origins have been disproved. For example, in 1688 Francesco Redi performed an experiment which refuted the notion that flies come from rotting meat--Redi discovered that flies actually come from worms that hatch from eggs laid in rotting biological matter which subsequently develop into flies. The recognition that flies come from eggs rather than meat fostered our early understanding of biological development, but one theory of spontaneous generation had to die before the advance was made.

Sermonti recounts that the field became stalled when the early evolutionist Comte de Buffon imagined that everything from fleas to the hippopotamus emerged from the primordial slime. Providing an Italian perspective on the history of biology, Sermonti explains that an Italian naturalist named Spallanzani refused to just accept spontaneous generation as the easy answer, and through a series of carefully observed experiments, came to the conclusion that "omne vivium ex ovo" (all life comes from eggs). Spontaneous generation was finally disproved by Pasteur's experiments nearly a century later. This was a fact lamented by Darwin, who claimed that Pasteur "denied spontaneous generation." Despite Pasteur's "denial," biology progressed.
