As used by author Jonathan Whitcomb, "Evolutionary Boundary" refers to a limitation of macroevolutionary potential, shown by a series of mathematical simulations in which immediate competition is distinguished from long-term major-biological-change competition.

Much of the credibility of Darwin's General Theory of Evolution is based upon a generalized idea of Natural Selection acting upon populations. Neo-Darwinism involves mutational changes that have been theorized to have caused sub-populations to develop differences which, when combined with later mutational changes, eventually add up to major transformations. The generalization is in mixing the idea of immediate survivability with the idea of long-term benefits of new organs or other biological structures.

In reality, when an organism experiences a mutational change, there are three relevant results possible: Immediate competitiveness is increased, the beginning of a new biological structure is started (or continued), or there is a combination of the first two. Any major change must occur in stages, and this can be calculated with simple formulas.

According to Whitcomb, it is the number of reproductive cycles (how many times reproduction occurs), rather than how long life has existed, that allows any potential credibility for macroevolution. His simulations, with an original population of 1029, showed that no major step in macroevolutionary development could reasonably take place. Natural Selection, according to his calculations, makes macroevolution practically impossible, even in a simulated environment more ideal than any natural environment presently found on the earth. "Survival of the Fittest" actually prevents any major change in biology.[1]
