Macroevolution means change "at or above the species level." Darwin's finches is the classic example of macroevolution. A more novel example can be found when a plant asexually reproduces and has an error in meiosis resulting in polyploidy. The offspring is phenotypically similar to the parent, but it cannot sexually reproduce with other plants of the parent species because it has more than the normal set of chromosomes. If it can't reproduce with a certain species, then it is distinct of that species. A new creation of a species is, you guessed it, macroevolution. Another example can be found when one population splits into two due to geographic barrier (i.e. geographic isolation). If sufficient time has lapsed and these two populations are reunited, failure to successfully reproduce indicates that these two groups have become two different species. Macroevolution at work yet again.
We Creationists simply agree with both of them and argue that neither proposed mechanism for macro evolution is capable of creating the complexity of life.
You really put a smile on my face with that comment. It was worded very well. I ask you one question - under the scientific method, can you test your creationism in the lab? Like I said to GourmetDan, I don't care whether you believe in it or not, it's not my business. But, if you claim it's science, then I'd like to know just how you can test it.
Thanks for your kind reply - I can see that definition’s are going to be key - I was (probably incorrectly) using the term Macro-Evolution to refer the change of one species into another - such as a fish into an amphibian. I agree with you that species frequently reach a point where they can no-longer interbreed. Where I would disagree is that I don’t see evidence of organisms developing new and beneficial genetic traits - that didn’t already exist in the gene pool - through natural selection.
In order for natural selection to develope a more complex organism it must have the ability to get significant benefits out of a progressive series of small changes to the genetic code. This presents a problem since the genetic code is much like a computer code and many base pairs would have to be changed to code for a new beneficial protein. If only some of those base pairs are changed correctly the changes would not provide any benefit and thus not be supported by natural selection.
In answer to your last question - I would say that creationism is testable in much the same way that evolution is. You can’t reduplicate it but you can look at the fossil record and the complexity of life and see if it is consistant with the view or not. Intelligent Design is simply a theory that much of the complexity of the genetic information contained in the DNA could not have been developed over time by random mutation + natural selection. So, it could be disproved by expiraments which show beneficial new proteins devoloping over time by random mutation + natural selection. Probably the easiest way to do these expiraments would be with Bacteria which have really short lifespans.
