Sometimes a creationist will say “there are no transitional species” or “animals do change, but one species never changes into another.” While I appreciate the sentiment, these claims are not true. In reality, new species do arise over time – a phenomenon we call speciation. Secularists sometimes claim that speciation is proof of Darwinian evolution, but this too is an error. All of these mistakes can be eliminated when we distinguish between species and kinds.
What exactly is natural selection? Is it the same as evolution? Does it really occur? And who came up with the idea? Unfortunately, a few creationists have greatly misunderstood natural selection, and have used faulty arguments to try to convince others of their misunderstanding. It is important that we understand this topic properly, both from a scientific perspective and from a biblical perspective, so that we do not inadvertently promote error.
Natural-selection-deniers make some claims that are directly contrary to the Bible. Furthermore, they tend to misunderstand the concept of biological adaptation, and make basic errors in logic. In this article, we will explore these errors, and how they might have been avoided if proper scientific protocol had been followed.
In the previous two articles, we have examined the principle of natural selection – the observation that organisms better suited to their environment will tend to survive and reproduce more successfully than those organisms less suited. In this third installment we will contrast the claims of “continuous environmental tracking” with what the Bible teaches concerning adaptation.
One of the many scientific lines of evidence against neo-Darwinian evolution involves the concept of irreducible complexity. Microbes, plants, fungi, animals, and human beings all have bodies that are composed of extremely complex microscopic machinery. The different parts of a biological cell are interdependent. Hence, neo-Darwinian evolution is incompatible with irreducible complexity.
