All of this talk about no evidence existing for macroevolution is wrong. There is evidence; you just are not aware of it.
First, macroevolution is evolution at or above the species level. That means speciation or the formation of new species is a type of macroevolution. In fact, speciation is a sufficient and necessary condition of macroevolution. Second, evidence of species formation has been observed (1) directly, as in the instantaneous process of speciation by polyploidy, or (2) indirectly, as in shared genetic, morphological, physiological, behavioral, and ecological traits seen in groups of species that are thought to be linked by origin. The latter, indirect method is the common way to infer macroevolution in cases in which the process of speciation simply takes too long to observe directly, such as when allopatric speciation occurs. What else could be done when the process takes far longer than many consecutive lifetimes of the observers???
In other words, when it is reasonable to expect to see direct evidence of macroevolution, as in speciation by polyploidy, such direct evidence is seen. When it is unreasonable to expect to see direct evidence of macroevolution, as in allopatric speciation, such direct evidence is not seen. But in this case, there is much indirect evidence of it having occurred.
