What is the difference between micro-evolution and macro-evolution?

Clearly some bacteria are becoming immune to our antibiotics, and some insects are becoming immune to our insecticides. Creationists call this microevolution.

Creationists say we accept microevolution, it is clearly observable, we reject macroevolution which is not observable.

Evolutionists say that macroevolution occurred over long periods of time but can not be observed currently because it is a slow process.

This distinction is important for practical reasons. Evolutionists claim that creationists ignore important issues like bacteria becoming immune to antibiotics, but because creationists generally accept microevolution this does not have to be a problem as long as the creationists are well informed about their own belief system.

From the Community of Evolutionary Biologists:

The difference is illusory. The following quote sums up the "difference' from the point of view of evolutionary biology:

The words "microevolution" and "macroevolution" are relative terms, and have only descriptive meaning; they imply no differences in the underlying causal agencies. " -Theodosius Dobzhansky, (1951) Genetics and the Origin of Species, Third Edition, Revised, p. 17
