More on Micro and Macro Evolution:
Quote:
From TalkOrigins
There is no difference between micro- and macroevolution except that genes between species usually diverge, while genes within species usually combine. The same processes that cause within-species evolution are responsible for above-species evolution, except that the processes that cause speciation include things that cannot happen to lesser groups, such as the evolution of different sexual apparatus (because, by definition, once organisms cannot interbreed, they are different species).

From TrueOrigins:
[He] conveniently fails to mention whether by “change in a gene pool over time” he means exactly that (i.e., genetic variation, which is often called “micro-evolution”), or whether he means “macro-evolution”—which is something entirely different. The postulation of “macro-evolution” (i.e., the emergence of entirely new and more “advanced” features through innumerable, completely new genetically-defined traits) is not to be confused with genetic variation (i.e., “micro-evolution”), which is the appearance and/or disappearance of existing and/or potential genetic traits through recombination of existing genetic code. Proponents of evolutionism often fail to note the important difference between these two, simply calling them both “evolution,” and thereby deliberately blurring the distinction between them.
