Evolution: Micro vs. macroevolution (Introduction)

A vast difference. We have no examples of macroevolution:-http://p2c.com/students/blogs/kirk-durston/2015/05/microevolution-vs-macroevolution-two-mistakes-"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. The reason that macroevolution has never been observed is that it requires statistically significant levels of novel genetic information. It is extremely difficult to achieve, but Darwinian theory predicts that genetic information can significantly increase over time. Falsifiable predictions can be made which we will examine later in this series. In order to clearly distinguish between microevolution and macroevolution in a rigorous scientific way, let me propose the following definitions, which I will continue to use:-"Microevolution: genetic variation that requires no statistically significant increase in functional information.-"Macroevolution: genetic change that requires a statistically significant increase in functional information."
