Not by Chance! has 59 ratings and 10 reviews. Qhlueme said: Spetner, PhD in physics and years of specialized study in organic evolution, takes the reader. The core of Dr. Lee Spetner’s chal- lenge to neo-Darwinian theory (NDT) is in chapters 4 and 5. He points out that evo- lutionists have repeatedly stressed that. Remarkably Spetner does not straightforward deny macro-evolution, he claims that.

The new book provides some wonderful arguments that challenge common descent and neo-Darwinian explanations of evolution.
Spetner goes through many examples lfe non-random evolutionary changes that cannot be explained in a Darwinian framework. Whatever the case, these abilities appear to be built-in mechanisms designed to allow an organism to adapt to a changing environment. An organism thus has the built-in ability to adapt to a new environment heritably by altering its DNA.
These adaptations occur just when they are needed, because they are triggered by an input from the new environment. Since they are triggered by the environment, their occurrence in a population s not rare.
They will occur in a large fraction of the population, leading to rapid evolutionary changes — possibly even in one generation!
If such adaptive changes had to be achieved by random DNA copying errors point mutationsthey would require long expanses of time, if they could be achieved at all. If comparing all possible biological features yields the same tree, then the tree could have some objective reality. Richard Dawkinspp.

Phylogenetic trees based on different genes are hot to give contradictory results. There was hope that the use of whole genomes, or at least large portions of genomes, for phylogenetic studies would resolve those contradictions, but that only made the problem worse. It is, however, an invention. It was invented solely to avoid addressing the failure of phylogenetic trees to support Common Descent.
There is no theoretical support for convergence, and whatever evidence has been given for it is the product of a circular argument. Richard Dawkins seems to revel in describing numerous examples of convergent evolution without realizing that any of those examples destroy his case for evolution.
Spetner goes on to list nearly xhance pages worth of striking examples of convergent evolution.
Under the NREH, they are not surprising but expected. Many other topics are covered in The Evolution Revolution. I highly recommend this short, up-to-date, well-informed, and well-written book for a review of some key, compelling evidence showing that species did not arise through neo-Darwinian mechanisms. Similar physical mechanisms are used to transmit sound waves from the ear to the brain in both vertebrates and certain insects.
