From the site right at the beginning:
"Microevolution - Unequivocally proven through numerous scientific studies. Includes concepts such as mutation, recombination, natural selection, etc.
Macroevolution - Extrapolation of microevolution to account for all changes in body designs, speciation, appearance of new phyla, etc."
Now, notice that they say macroevolution is speciation. Well, speciation has been seen in numerous studies, therefore macroevolution is as "unequivocally proven" as microevolution.
What's more, as soon as you have a new species, that's it. Changes in body designs and the appearance of new phyla are simply speciation.
"But we must ask, what exactly are these genera, families, orders, and so on? It was clear to Darwin, and it should be obvious to all today, that they are simply ever larger categories used to give names to ever larger clusters of related species. That's all these clusters, these higher taxa, really are: simply clusters of related species.
Thus, in priniciple the evolution of a family should be no different in its basic nature, and should involve no different processes, from the evolution of a genus, since a family is nothing more than a collection of related genera. And genera are just collections of related species. The triumph of evolutionary biology in the 1930s and 1940s was the conclusion that the same principles of adaptive divergence just described -- primarily the processes of mutation and natural selection -- going on within species, accumulate to produce the differences we see between closely related species -- i.e., within genera. Q.E.D.: If adaptive modification within species explains the evolutionary differences between species within a genus, logically it must explain all the evolutionary change we see between families, orders, classes, phyla, and the kingdoms of life.
