Life cannot have had a random beginning ... The trouble is that there are about 2000 enzymes, and the chance of obtaining them all in a random trial is only one part in 10^40,000, an outrageously small probability that could not be faced even if the whole universe consisted of organic soup.

Natural selection eliminates and maybe maintains, but it doesn't create... Neo-Darwinists say that new species emerge when mutations occur and modify an organism. I was taught over and over again that the accumulation of random mutations led to evolutionary change [which] led to new species. I believed it until I looked for evidence.

New mutations don't create new species; they create offspring that are impaired.

Organic life beneath the shoreless waves
Was born and rais’d in Ocean’s pearly caves
First forms minute, unseen by spheric glass,
Move on the mud, or pierce the watery mass;
These, as successive generations bloom,
New powers acquire, and larger limbs assume;
Whence countless groups of vegetation spring,
And breathing realms of fin, and feet and wing.

Dearest love, let me count the ways. Dismemberment, garroted, poisoned, drowned, named. I read that as soon as a species is named it begins its travels up the endangered list. Discovery meaning death.

Darwinism gives no moral guidelines about how we should live or how doctors should practice medicine. A Darwinian perspective on medicine can, however, help us to understand the evolutionary origins of disease, and this knowledge will prove profoundly useful in achieving the legitimate goals of medicine.
Randolph M. NesseThe fundamental core of contemporary Darwinism, the theory of DNA-based reproduction and evolution, is now beyond dispute among scientists. It demonstrates its power every day, contributing crucially to the explanation of planet-sized facts of geology and meteorology, through middle-sized facts of ecology and agronomy, down to the latest microscopic facts of genetic engineering. It unifies all of biology and the history of our planet into a single grand story. Like Gulliver tied down in Lilliput, it is unbudgeable, not because of some one or two huge chains of argument that might–hope against hope–have weak links in them, but because it is securely tied by hundreds of thousands of threads of evidence anchoring it to virtually every other field of knowledge. New discoveries may conceivably lead to dramatic, even 'revolutionary' shifts in the Darwinian theory, but the hope that it will be 'refuted' by some shattering breakthrough is about as reasonable as the hope that we will return to a geocentric vision and discard Copernicus.
