The famous nineteenth century naturalist Charles Darwin assumed that because micro-evolution occurs in nature then macro-evolution must also be possible, but the modern scientific evidence from genetics supports only the possibility of micro-evolution, or limited biological variation, occurring in living things. For example, no matter how many different races or varieties of dogs come into being they will always remain dogs and not change or evolve into some other kind of animal. Even the formation of an entirely new species of plant or animal from hybridization will not support Darwinian evolution since such hybridization does not involve any production of new genetic information but merely the recombination of already existing genes. Modifications or recombinations of already existing genes for already existing traits have been shown to occur in nature but never the production of entirely new genes for entirely new traits. This is true even with genetic mutations. For example, mutations in the genes for human hair may change the genes so that another type of human hair develops, but the mutations won't change genes for human hair so that feathers, wings, or some other entirely new traits develop. Mutations may even cause duplication of already existing traits (i.e. an extra finger, toe, etc. even in another part of the body!), but none of these things qualify as being new traits. The genes already exist in every species for micro-evolution to be possible. The reader should be aware, however, that most biological variations within a species are not because of mutations but, rather, because of new combinations of already existing genes.
The theory of macro-evolution, on the other hand, teaches that there are no biological limits to variation and change. For example, macro-evolution teaches that over millions of years something like a dog evolved into an ape and then something like an ape evolved into a human being. But, unless the environment or Nature has the ability to perform genetic engineering such macro-evolutionary changes, as proposed by Darwin, are not possible - millions of years or no millions of years!
It is true that natural selection occurs in nature, but natural selection itself is not a creative force. Natural selection can only work with biological variations that are possible and which have survival value. Natural selection does not produce or generate biological variations. It is a passive process in nature. When a biological change or variation occurs which helps an animal to survive in its environment then that variation will be preserved and be passed on to offspring. That is called "natural selection". There is, of course, no conscious or active selection on the part of nature as some think. The term "natural selection" is simply a figure of speech. Natural selection may explain how a biological trait or variation survives but it does not explain how biological traits or variations originate. As one individual has said, "Natural selection may explain the survival of the fittest but it doesn't explain the arrival of the fittest!" Natural selection explains only a small part of reality. In any case, the real issue is not natural selection but, rather, what biological variations are naturally possible because natural selection can only "select" from those biological variations that are possible in nature.
Many have confused natural selection with evolution itself. Natural selection works with evolution but it does not produce evolution (that is it does not design or generate biological traits and variations). It's true that natural selection itself does not work by chance but natural selection depends on chance to produce the biological variations from which it can "select".
All observed biological traits and variations are the result of new combinations of already existing genes or the result of modifications (mutations) of already existing genes. This allows for only limited biological variations to occur. Evolutionists, however, believe that, if given enough time, random or chance mutations in the genetic code, caused by random environmental forces such as radiation, will produce entirely new traits and variations which natural selection can then act upon. However, mutations are accidents in the sequential molecular structure of the genetic code and they are almost always harmful, as would be expected from accidents. Of course, just like some earthquakes that don't do any damage to buildings, there are also mutations that don't do any biological harm. But, even if a good mutation does occur for every good mutation there will be hundreds of harmful ones with the net result over time being disastrous for the species. Natural selection would have no chance. It wouldn't get to first base!
Even a half-evolved and useless organ waiting millions of years to be completed by random mutations would be a liability and hindrance to a species - not exactly a prime candidate for natural selection. In fact, how could species have survived over, supposedly, millions of years if their vital (or necessary) organs were still in the process of evolving! Scientist Dr. Walt Brown, in his fantastic book "In The Beginning", makes this point by saying "All species appear fully developed, not partially developed. They show design. There are no examples of half-developed feathers, eyes, skin, tubes (arteries, veins, intestines, etc.), or any of thousands of other vital organs. Tubes that are not 100 percent complete are a liability; so are partially developed organs and some body parts. For example, if a leg of a reptile were to evolve into a wing of a bird, it would become a bad leg long before it became a good wing."
In any case, there is no scientific evidence whatsoever that the environment has the ability to generate entirely new genes which would program for the development of entirely new traits in species. It would require genetic engineering to accomplish such a feat. For those who are not read-up on their biology, a little information on genes would be helpful here. What we call "genes" are actually segments of the DNA molecule. DNA, or the genetic code, is composed of a molecular string of various nucleic acids (chemical letters) which are arranged in a sequence just like the letters found in the words and sentences of a book. It is this sequence of nucleic acids in DNA that tells the cells of our body how to construct (or build) various proteins, tissues, and organs such as nose, eyes, brain, etc. If the nucleic acids in the genetic code are not in the correct sequence then malfunctioning, or even worse, harmful proteins may form causing serious health problems and even death.
There is no law in science that nucleic acids have to come together in a particular sequence. Any nucleic acid can just as easily bond with any other. The only reason for why nucleic acids are found in a particular s
