Mutations simply produce new varieties of already existing traits. For example, mutations in the gene for human hair may change the gene so that another type of human hair develops, but the mutations won't change the gene so that feathers or wings develop.
Sometimes mutations may trigger the duplication of already existing traits (i.e. an extra finger, toe, or even an entire head, even in another area of the body!). But mutations have no ability to produce entirely new traits or characteristics.
Furthermore, only those mutations produced in the genes of reproductive cells, such as sperm in the male and ovum (or egg cell) in the female, are passed on to offspring. Mutations and any changes produced in other body cells are not transmitted. For example, if a woman were to lose a finger it would not result in her baby being born with a missing finger. Similarly, even if an ape ever learned to walk upright, it could not pass this characteristic on to its descendants. Thus, modern biology has disproved the once-held theory that acquired characteristics from the environment can be transmitted into the genetic code of offspring.
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 possessed genes to produce all the variety and races of men. You and I today may not carry the genes to produce every variety or race of humans, but humanity's first parents 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, 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.
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.
Science cannot prove we're here by creation, but neither can science prove we're here by chance or macro-evolution. No one has observed either. They are both accepted on faith. The issue is which faith, Darwinian macro-evolutionary theory or creation, has better scientific support.
If some astronauts from Earth discovered figures of persons similar to Mt. Rushmore on an uninhabited planet there would be no way to scientifically prove the carved figures originated by design or by chance processes of erosion. Neither position is science, but scientific arguments may be made to support one or the other.
What we believe about life's origins does influence our philosophy and value of life as well as our view of ourselves and others. This is no small issue!
Just because the laws of science can explain how life and the universe operate and work doesn't mean there is no Maker. Would it be rational to believe that there's no designer behind airplanes because the laws of science can explain how airplanes operate and work?
Natural laws are adequate to explain how the order in life, the universe, and even a microwave oven operates, but mere undirected natural laws can never fully explain the origin of such order.
Of course, once there is a complete and living cell then the genetic program and biological mechanisms exist to direct and organize molecules to form into more cells. The question is how did life come into being when there was no directing mechanism in Nature. An excellent article to read by scientist and biochemist Dr. Duane T. Gish is " A Few Reasons An Evolutionary Origin of Life Is Impossible ".
Read also the author's article "Textbook Biology's Origin of Life Deception".
There is, of course, much more to be said on this subject. Scientist, creationist, debater, writer, and lecturer, Dr. Walt Brown covers various scientific issues ( i.e. fossils, "transitional" links, biological variation and diversity, the origin of life, comparative anatomy and embryology, the issue of vestigial organs, the age of the earth, etc. ) at greater depth on his website at www.creationscience.com .
On his website, Dr. Brown even discusses the possibility of any remains of life on Mars as having originated from the Earth due to great geological disturbances in the Earth's past which easily could have spewed thousands of tons of rock and dirt containing microbes into space. In fact, A Newsweek article of September 21, 1998, p.12 mentions exactly this possibility.
An excellent source of information from highly qualified scientists who are creationists is the Institute for Creation Research in San Diego, California. Also, the reader may find answers to many difficult questions concerning the Bible (including questions on creation and evolution, Noah's Ark, how dinosaurs fit into the Bible, etc.) at www.ChristianAnswers.net.
It is only fair that evidence supporting intelligent design or creation be presented to students alongside of evolutionary theory, especially in public schools which receive funding from taxpayers who are on both sides of the issue. Also, no one is being forced to believe in God or adopt a particular religion so there is no true violation of separation of church and state. As a religion and science writer, I encourage all to read my Internet article "The Natural Limits of Evolution" at my website www.religionscience.com for more in-depth study of the issue.
The author, Babu G. Ranganathan, is an experienced Christian writer. Mr. Ranganathan has his B.A. degree with concentrations in theology and biology. As a religion and science writer he has been recognized in the 24th edition of Marquis Who's Who In The East.
