For example, evolutionists believe that the bat evolved from mice or rats because the bodies of these animals are very similar. A teacher of evolution using the mutation and natural selection method would explain this process in a similar manner to the following example:
"Over millions of years a mutation occurred in which a mouse was born with webbed front feet. As this mouse mated, other web-footed mice were born. In this manner, web-footed mice gradually became established. Over millions of years a second mutation took place which affected this same group of web-footed mice, doubling the size of their webbed feet. A similar series of mutations took place every several million years until eventually, present-day bats with large wings developed."
If we examine this explanation we need to note that mutations occur only once in an estimated ten million cell divisions. The odds of two mutations happening to one gene are one in a hundred trillion cell divisions.
To develop populations large enough before another mutation could reasonably be expected to occur would require millions of years. How would the first mice with their awkwardly webbed feet have survived for millions of years? How would the succeeding generations with half feet and half wings have been able to flee from their predators fast enough to survive for another period of millions of years until the next beneficial mutation would have occurred? How would natural selection actually work against species experiencing mutations of this drastic nature, if they ever would have occurred?
While minor mutations do occur, creationists believe this would never provide a reasonable explanation for the vast complexity of plant and animal species that we observe in the world today. They deny a reasonably possible "random mutation and natural selection theory" for these reasons:
a. A change from one species to another through mutations has never been observed, but only new strains of the same species.
b. A mutated form of a species is almost always weaker than its natural type.
Natural selection - The theory that nature tends to keep and increase those species having characteristics best fitted for survival in their
Believing in evolutionary theories requires tremendous faith in the unseen. Why?
Strains - Varieties; stocks; races; variations within the same species
