Darwinian Evolution presupposes that the mutation or the change is small, and the mutation process in passed down only via the mechanism of natural selection. In other words, a new trait must not be so complex and the change so huge as to cause people to suspect that there might be some directed process, or an Intelligence causing the change; other than natural selection that would cause the change.
Evolution says that it is impossible to evolve a complex organ like a fully developed human eye in a single generation. The development of a complex organ must take place slowly, one minor change at a time, one minor change per generation. This also implies that the minor changes must be commulative, or additive. One small minor change within each generation that adds up generation after generation until it becomes an organ as complex as an eye. I reject the basis of your argument. The above is an archaic assumption as follows. * * *Punctuated equilibrium* *Punctuated equilibrium* (also called *punctuated equilibria*) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called *stasis*. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another. Punctuated equilibrium is commonly contrasted against the theory of phyletic gradualism, which states that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous. In 1972, paleontologists Niles Eldredge and Stephen Jay Gould published a landmark paper developing this theory and called it *punctuated equilibria*. Their paper built upon Ernst Mayr's theory of geographic speciation, I. Michael Lerner's theories of developmental and genetic homeostasis,[4]<http://en.wikipedia.org/wiki/Punctuated_equilibrium#cite_note-3>as well as their own empirical research. Eldredge and Gould proposed that the degree of gradualism commonly attributed to Charles Darwin is virtually nonexistent in the fossil record, and that stasis dominates the history of most fossil species.
