Is it Christian Doctrine to say that macroevolution is not the same as microevolution? We read in Genesis that the world was created in seven days. 

This article states:


  Contrary to claims by creationists, macro and microevolution describe fundamentally identical processes on different time scales.


[The assumption being that more than seven days are required for the changes to bring about all the living beings we see today.]

My question is is it Christian Doctrine to say that macroevolution is not the same as microevolution?
Doctrine does not make claims about the definitions that biologists (or others) use.

If someone wanted to assert that the earth is billions of years old, then someone's doctrine may contradict that assertion, but it is not a doctrinal assertion to argue about what is meant by macro- or microevolution.

If someone has an issue with macroevolution (e.g. because its logical implications contradict their doctrine), it is more likely that they claim that there isn't much in the way of proof that macroevolution has actually happened and that it is very, very improbable. Microevolution has been observed, whereas macroevolution is a theory imposed upon historical science.
