| What is wrong with natural selection? |
Let us first have a look at the problems the author has with natural
selection and later what his explanation is for the evolutionary process.
Lima does not deny the existence of selection, but he denies that it has anything to do with evolution. "Selection is a word that must be removed from the vocabulary of biology" (page xviii) because it is an abstract concept and it is not material. "Selection cannot be measured in well-defined units such as millimetres, it cannot be poured into a vial and cannot be weighed on a balance" (pxviii). These are outrageous criterions. If all abstract concepts should be removed from science, there wouldn't be any scientific theory at all left. What about the concept of a 'gene'? The point is that 'abstract' is not the same as 'vague'. Numbers and mathematics are abstract but not vague! They are exact, precise. Is 'gravitational field' or 'electromagnetic field' a material thing? Is it abstract? I hope that Lima doesn't want to remove it from physics! There could be something wrong with the concept of natural selection, but Lima is unable to point it out. He used the wrong arguments as far as I can see. The concept 'lethal mutation' means that an individual with that mutation dies. Well, that is natural selection in action. Without natural selection the concept 'lethal mutation' has no meaning at all. Natural selection means differential reproduction of genotypes. This can be exactly measured in the laboratory and sometimes in the field. This is what population genetics is all about. But that word is not in his vocabulary. Lima does know about differential reproduction and rightly states that differential reproduction is not necessarily the mechanism of evolution. Of course not necessarily, but there could be evidence that selection is the mechanism of evolution, isn't it? And there happens to be evidence. If Lima only did read the evidence for natural selection presented by the anti-Darwinist Denton (Evolution: a Theory in Crisis), he would be convinced! I do agree with Lima (contrary to orthodox neo-Darwinism) that natural selection and mutation are not sufficient to explain all diversity of life forms on earth. But affirming that is quite another thing, than to remove it from biology. If selection exists, one cannot remove it from biology without making biology incomplete. Even a creationist like Phillip Johnson (Darwin on Trial) recognises natural selection as the most important Darwinian concept. And more than 50 years earlier the creationist Frank Lewis Marsh accepted micro-evolutionary change (Evolution, Creation and Science,1944). Indeed, Lima-de-Faria is exceptional among the critics of evolution in totally rejecting natural selection. | ||
| Do crystals contain the secret of life? |
If Lima-de-Faria holds that crystals are the secret of life, he must be wrong according
to writers such as Hubert Yockey, William Dembski and Dean Overman.
Crystals contain order, not complexity. Complexity is unique to life, not order.
Crystallography, high polymer chemistry and physics are separated from biology by a wide gap. (2) Erwin Schrödinger (1944) remarked in his famous What is life? that the genetic material, whatever its chemical structure, must be an 'aperiodic crystal'. "The genetic material must resemble a crystal in being stable and relatively inert, but it must also be 'aperiodic', in the sense of being composed of several different kinds of unit and not just of one kind of unit like a crystal of salt. The reason is that a string of identical units cannot convey information, whereas a string of dissimilar units can." (3).
