Biological Scientific Evidence for Creation
Natural Selection and Extinction
Natural selection is a mechanism for change in populations that occurs when organisms with favorable genes suitable for a specific environment are able to survive, reproduce, and pass these genes on to the next generation through natural selection Natural selection (commonly known as “survival of the fittest,” adaptation, speciation, variation, or microevolution) is the genetic process within populations which selects gene traits from an existing gene pool best suited for a given environment. For example, DDT resistance in insects, change in dominant color, and long hair versus short hair are NOT evolutionary change but merely reshuffling of genes within the existing gene pool that was originally present in a certain “kind” of animal population. No one has ever observed uphill drift or the addition of genetic information to the gene pool. Genetic drift has always been “downhill.”. Natural selection is also commonly known as “survival of the fittest.” (Other common terms include microevolution, adaptation, and speciation.)
Contrary to popular belief, natural selection, survival of the fittest, or microevolution is Not Evolution. It is merely a genetic process within populations which selects gene traits from an existing “gene pool” in the original “kind” of animal best suited for a specific environment. A gene pool for a particular “kind” of animal is genetic information already present in the “kind” population. Gene shuffling (reshuffling or genetic recombination) of the same information in many different ways in response to a specific environment (or as a result of artificial breeding) will result in much variation or speciation in any “kind” of plant or animal population.
For example, the thick skin and heavy long white coat of polar bears allow these animals to survive in colder regions of the world. Over many generations thick skin, long-haired bears pass on their genetic information whereas other subgroups of bears with shorter hair and thinner skin have long since died. Natural selection does not change the total capacity of the genome to store information, but once the maximum number of long-haired and thick-skin genes has accumulated in that line, they will occupy positions formerly held by short-haired and thin-skin genes. So the thick skin and long-haired bears have less genetic variety (that is, there is a loss of genetic information) than its original “kind” ancestors, which had information for both short and long hair.
The original “bear kind” or “dog kind” or “cat kind” which was created with a large, diverse gene pool with no original defects, could vary simply by recombination of the original genetic information because of an extreme or unique environment. Most people are unaware that natural selection or survival of the fittest is actually a thinning out process that leads to loss of genetic information.
Also, natural selection is why physical characteristics of people tend to correspond with their environment. Modern racial groups have notably different morphological features such as skin and hair color. Variations in human groups, including all animal groups, are not evolutionary changes but, as previously stated, reshuffling of genes within the already existing “gene pool” that was present in the original “kind” population in response to the environment.
Darker skin is able to dissipate UV radiation as heat and lighter skin is able to absorb more vitamin D through exposure to sunlight. Using skin color as an example, natural selection is in response to a specific environment. Mankind has only one skin coloring pigment —melanin, and the shade (brown) depends on how much pigment a person (or subgroup) produces. Human subgroups with more melanin (darker skin) tend to survive better in equatorial regions because of less frequent skin cancer risk—and subgroups with less melanin (lighter skin) tend to survive better in polar regions because of less frequent vitamin D deficiency.
Although adaptive specialization significantly improves the survival potential of the species, it makes the species prone to extinction Extinction is the cessation of existence of a species or group of animals (or plants). It is usually brought about by adaptation to a specific environment following a drastic change in that environment if climatic conditions change. Simply, animals with “best suited” genes to a specific environment will continue to survive and animals with “least suited” genes will eventually die. Animals adapted to a specific environment will also die if the climate should drastically change.
Dinosaurs and other animals became extinct because of a drastic change of environment—from a very mild antediluvian (pre-worldwide flood) environment to a world overwhelmed by catastrophic flood followed by the Great Ice Age. More information about dinosaurs during the pre- and post-antediluvian periods, and the onset of the Great Ice Age, is presented in the book, evolution – The Greatest Deception in Modern History.
Reputable scientists know that natural selection (or survival of the fittest, adaptation, or speciation) is not evolution but, rather, leads to loss of genetic information. Most “examples” of evolution are nothing more than adaptation to their particular environment. If evolution were ever to succeed from molecules to man, the process would need a way to create new, complex genetic programs, or information—it needs new information to arise by natural “uphill” progression contrary to the Second Law. This has NEVER been observed in nature.
