From Kirk Durston, here:
The definition of macroevolution is surprisingly non-precise for a scientific discipline. Macroevolution can be defined as evolution above the species level, or evolution on a ‘grand scale’, or microevolution + 3.8 billion years. It has never been observed, but a theoretical example is the evolution from a chordate eel-like creature to a human being. Many people who embrace Darwinian evolution confidently state that evolution is a proven fact, not a theory. They say this in the basis of thousands of papers discussing microevolution. Herein lays the second mistake … the assumption that because variation/microevolution is such an overwhelmingly proven fact that, therefore, macroevolution must be as well.
Macroevolution is very different from microevolution. The reason there are so many countless observations of variation/microevolution is that it requires no statistically significant levels of novel genetic information; it is trivially easy to achieve. More.
And macroevolution is the road to Arcturus, right?
