According to evolutionists, natural selection and mutations are the only two ways that new species have ever been made. In this article, you will learn that mutations cannot do it either. Evolutionists who believe that natural selection accomplished the task are called Darwinists. Evolutionists who believe that only mutations can make the evolutionary changes are called Neo-Darwinists. Many evolutionists have recognized that natural selection could not possibly produce trans-species changes, so they declare that mutations must have produced the multitude of separate species found in our world today.
Mutations are very rare.
They hardly ever occur in the natural world. Their very rarity dooms the possibility that they could produce the prolific number of plant and animal species found in our world. Mutations are simply too rare to have produced all the necessary traits of even one life form, much less millions. 2 - Random effects. They are never purposive or directed.
