what is the difference between microevolution and macroevolution?

Hello and Good Evening Everyone,

         I am wondering what the difference or differences are between microevolution and macroevolution.  Could change within a species caused by a mutation be an example of microevolution?  And, what about macroevolution?  Could change as a result of natural selection be an example of it?

        Any shared input to this post will be greatly appreciated.

        Thank you

        George

Hello and Good Morning

           Thank you for your feedback.  While I have not had the opportunity to thoroughly go over the information contained within the link given by ozo, I am certainly looking forward to doing it.  Perhaps this is covered within the resource provided, but, I am wondering if there is a computer model which substantiates the claims made within the theories of microevolution and macroevolution.  For instance, there are computer simulation models which lend support to various theories about weather patterns.  Realizing that biological systems are certainly much more complex than weather systems, there may not not be any computer simulation programs that do this.

             Seeing that I have not evaluated the resource provided, I apologize if my followup question is addressed within it.  If not, could someone shed some insights upon it?

              Thank you

Hello

          Thank you for putting so much research into my question.  Basically, I am interested in any model or models which support the theories of microevolution and macroevolution.

There are many, of which I gave a few examples hoping it would lead to a better idea of which kinds of models you were interested in.
Microevolution tends to be short term and macroevolution tends to be long term, so a model covering both would probably be large and run a long time.
Models can also focus on particular environments, particular organisms, particular populations, particular fossils, particular experiments, particular genes, particular features,...
They may address mathematics, physics, chemistry, genomics, proteomics, embryology, morphology, paleontology, systematics, ecology, pharmacology, epidemiology, agriculture, sociology,...
They may be written in particular programming languages, the intent may be academic, recreational, commercial, medical,...
