Why most scientists support the theory of evolution

In some circles, however, opposition to the concept of evolution has persisted to the present. The argument from design has recently been revived by a number of academics with scientific credentials, who maintain that their version of the idea (unlike Paley’s) is soundly supported by both microbiology and mathematics. These antievolutionists differ from fundamentalist creationists in that they accept that some species do change (but not much) and that Earth is much more than 6,000 years old. Like their predecessors, however, they reject the idea that evolution accounts for the array of species we see today, and they seek to have their concept—known as intelligent design—included in the science curriculum of schools.

Erasmus Darwin's work includes the following acceptance of heritable evolutionary change:-



It appears that on this visit Darwin actually gave an outline of his theory of evolution by natural selection to Lyell - who urged Darwin to prepare some account of his theory for publication on the grounds that Wallace might seem to be the originator of these views if his species variation work, as outlined in his by ALFRED R.

The geological discussion with which Part II begins corresponds to two chapters (IV and V) of the 1844 Essay.

And Behe may throw up his hands and say that he cannot imagine how the components that move proteins between subcellular compartments could have evolved, but scientists actually working on such systems completely disagree. In a 1998 article in the journal Cell, a group led by James Rothman, of the Sloan-Kettering Institute, described the remarkable simplicity and uniformity of these mechanisms. They also noted that these mechanisms “suggest in a natural way how the many and diverse compartments in eukaryotic cells could have evolved in the first place.” Working researchers, it seems, see something very different from what Behe sees in these systems — they see evolution.

New features require new variations. In the modern version of Darwin’s theory, these come from DNA mutations. Most DNA mutations are harmful and are thus eliminated by natural selection. A few, however, are advantageous — such as mutations that increase antibiotic resistance in bacteria and pesticide resistance in plants and animals. Antibiotic and pesticide resistance are often cited as evidence that DNA mutations provide the raw materials for evolution, but they affect only chemical processes. Major evolutionary changes would require mutations that produce advantageous anatomical changes as well.

Wells contends that “Darwin’s theory cannot account for all features of living things,” but then, it doesn’t have to. Today scientists explain features of living things by invoking not only natural selection but also additional biological processes that Darwin didn’t know about, including gene transfer, symbiosis, chromosomal rearrangement, and the action of regulator genes. Contrary to what Wells maintains, evolutionary theory is not inadequate. It fits the evidence just fine.

Scientific theories, however, must fit the evidence. Two examples of the evidence for Darwin’s theory of evolution — so widely used that I have called them “icons of evolution” — are Darwin’s finches and the four-winged fruit fly. Yet both of these, it seems to me, show that Darwin’s theory cannot account for all features of living things.
