Life Sciences
Before considering how life began, we must first understand the term "organic evolution." Organic evolution, as theorized, is a naturally occurring, beneficial change that produces increasing and inheritable complexity. Increased complexity would be shown if the offspring of one form of life had a different and improved set of vital organs. This is sometimes called the molecules-to-man theory-or macroevolution. (See Figure 4 on page 6.) Microevolution, on the other hand, does not involve increasing complexity. It only involves minor chemical alterations or changes in size, shape, or color. Microevolution can be thought of as "horizontal" change, whereas macroevolution (if it were ever observed) would involve an "upward" and beneficial change in complexity. Notice that microevolution plus time will not produce macroevolution. [micro + time # macro]
Both creationists and evolutionists agree that microevolution occurs. Minor change has been observed since history began. Notice how often evolutionists give evidence for microevolution to support macroevolution. It is macroevolution, which requires new abilities and increasing complexity, that is at the center of the creation-evolution controversy. In this book, the term "organic evolution" will therefore mean macroevolution.
