By Bodie Hodge] "In evolutionary theory, mutations are described as the mechanism that fuels the engine of natural selection, creating new organisms as a result. However, the vast majority of mutations are either neutral or cause a loss of information in the genetic code of an individual...

Evolution teaches that mutations have accumulated over millions of years to increase the complexity of organisms on the earth. The Bible teaches that, as a result of Adam’s sin, all of creation is in a downward slide—including the genetic information that is in every living cell...

[T]he explanation of a genetic degradation since the Curse of Adam actually fits the evidence better than the evolution model of increasing complexity." Are mutations part of the “engine” of evolution? Hodge.
