The finches that some evolutionists claim to represent evidence of micro-evolution are actually an example of speciation. It is true that initially, the ancestors of the finches on the Galapagos Islands were rather few in number. However, some finches that arrived on the islands from the South American continent spread over the islands, and as a result of geographic isolation, variations began to predominate between the two groups. (See Geographic isolation.)
The speciation among these birds emerged at exactly this point. It has been seen that when birds belonging to different variations are brought back together again in any e way, they lose the instinct to mate with one another. This stems not from any biological difference, but from completely different behavior patterns. One bird does not regard as a potential mate another variation it has not previously lived together. As a result, these variations failure to interbreed stems not from their turning into biologically different species, but because their living in different geographical regions leaves them feeling no impulse to do so.
In an effort to use this observation to support their own theories, evolutionists propose a groundless, unscientific distortion along the lines of “Finches speciate among themselves thanks to geographic isolation. This means that if they are exposed to greater natural selection they will soon turn into totally different species.”
But this variation in finches has nothing to do with the formation of new species, as evolutionists maintain. The phenomenon consists of new variations within a species emerging through different gene combinations within the entire finch gene pool. The species is still the same species, and there is no question of any new genes—in other words, any new information—being added to the species’ gene pool.
To give an analogy of how evolutionists distort this evident truth on the genetic variation in finches for their own advantage, pick up a pack of playing cards and shuffle it a few times. No new or different cards will ever emerge. All that happens is that the order of the cards changes.
The variation within finches is exactly the same. No new gene is added to the these birds’ gene pool, and the finches newer turn into another species of bird. They merely exhibit variation within themselves. Many living things in nature display even extensive variations, but none of them is evidence for evolution.
