Micro-evolution: only evolution that is possible

The only evolution in nature that is possible and can be called science is micro-evolution, which is variations within biological kinds such as varieties of dogs, cats, horses and cows.

Macro-evolution, or variations across biological kinds, is not possible. Why is this so?

The genes exist in all species for micro-evolution but not for macro-evolution, and there is no scientific evidence that random genetic mutations caused by natural forces such as radiation can or will generate entirely new genes for entirely new traits. Random forces in nature have no ability to perform genetic engineering in order to bring about entirely new genes.

Random genetic mutations caused by environmental forces will not produce entirely new genes anymore than randomly changing the sequences of letters in a cookbook will change it into a book on astronomy.

Evolutionists have nothing else to rely on except random genetic mutations caused by random forces of the environment, such as radiation, to make their theory work.

Another major problem for macro-evolution is the issue of survival of the fittest. How can a partially evolved species be fit for survival? A partially evolved trait or organ that is not completely one or the other will be a liability to a species, not a survival asset.

Genetic similarities between species are no proof of common biological ancestry because it cannot be proved that these similarities are due to a common biological ancestry via chance mutations.

What if the similarities between species are due to a common designer who designed similar functions for similar purposes? Only genetic similarities within a biological kind can be used as proof of relationship.

It is not rational to believe that genetic information can come about by chance (i.e. random mutations) so it is much more logical to believe that genetic and biological similarities between species are because of a common designer rather than common ancestry.

It is true that natural selection occurs in nature, but natural selection itself does not produce biological variations. Natural selection is an entirely passive process in nature and can work only with biological variations that are possible and which have survival value. Natural selection is simply another way of saying that if a biological variation occurs which is helpful to an animal or plant's survival then that variation will be preserved ("selected") and be passed on. Of course, nature does not do any active or conscious selecting. The term "natural selection" is simply a figure of speech. The important thing to remember is that natural selection can only "select" from biological variations that are possible and which have survival value.

The fossil record contains fossils of only complete and fully-formed species. There are no fossils of partially-evolved species to indicate that a gradual process of evolution ever occurred. Even among evolutionists there are diametrically different interpretations and reconstructions of the fossils used to support human evolution from a supposed ape-like ancestry. In fact, all of the fossils, with their fancy scientific names, that have been used to support human evolution have eventually been found to be either hoaxes, non-human,or human, but not both human and non-human. Yet, many modern school textbooks continue to use these long disproved fossils as evidence for human evolution. Evolutionists once reconstructed an image of a half-ape and half-man (known as The Nebraska Man) creature from a single tooth! Later they discovered that the tooth belonged to an extinct species of pig! The "Nebraska Man" was used as a major piece of evidence in the famous Scopes Trial in support of Darwin's evolutionary theory.

Even if evolution takes millions and millions of years, we should still be able to see some stages of its process. But, we simply don't observe any partially-evolved fish, frogs, lizards, birds, dogs, cats among us. Every species of plant and animal is complete and fully-formed.

Another problem is how could partially-evolved plant and animal species survive over millions of years if their vital organs and tissues were still in the process of evolving? How, for example, were animals breathing, eating, and reproducing if their respiratory, digestive, and reproductive organs were still incomplete and evolving? How were species fighting off possibly life-threatening germs if their immune system hadn't fully evolved yet?

Young people, and even adults, often wonder how all the varieties and races of people could come from the same human ancestors. Well, in principle, that's no different than asking how children with different color hair ( i.e. blond, brunette, brown, red ) can come from the same parents who both have black hair.

Just as some individuals today carry genes to produce descendants with different color hair and eyes, humanity's first parents, Adam and Eve, possessed genes to produce all the varieties and races of men. You and I today may not carry the genes to produce every variety or race of humans, but Adam and Eve, did possess such genes.

All varieties of humans carry genes for the same basic traits, but not all humans carry every possible variation of those genes. For example, one person may be carrying several variations of the gene for eye color (i.e. brown, green, and blue), but someone else may be carrying only one variation of the gene for eye color (i.e. brown). Thus, both will have different abilities to affect the eye color of their offspring. Our bodies do not express every possible variation of the genes that we carry. One man having black hair may be carrying unexpressed genes for blond hair. Another man having black hair may not be carrying any unexpressed genes for different color hair. There are so many possibilities with genes and their combinations.

Some parents with black hair, for example, are capable of producing children with blond hair, but their blond children (because they inherit only recessive genes) will not have the ability to produce children with black hair unless they mate with someone else who has black hair. If the blond descendants only mate with other blondes then the entire line and population will only be blond even though the original ancestor was black-haired.
